Three authors becomes two names followed by et al. when cited in text

Question

I have the following biblatex setup:

\usepackage[backend=biber, style=apa, citestyle=authoryear, natbib=true, maxcitenames=1]{biblatex}

I have a citation with three authors, and when I use \citet*{thompson_feature_2005} I correctly get Thompson, Hamilton and Rust (2005) in the text.

But when I use \citet{thompson_feature_2005} (without the *) I incorrectly get Thompson, Hamilton et al. (2005), it should be Thompson et al. (2005).

The reason I use the words correctly and incorrectly is that this is the only citation that behaves this way. Other three author citations works like intended.

---

Heres the biblatex for this particular citation which doesn't work as intended:

@article{thompson_feature_2005,
    title = {Feature Fatigue: When Product Capabilities Become Too Much of a Good Thing},
    volume = {42},
    issn = {0022-2437, 1547-7193},
    url = {http://journals.sagepub.com/doi/10.1509/jmkr.2005.42.4.431},
    doi = {10.1509/jmkr.2005.42.4.431},
    pages = {431--442},
    number = {4},
    journaltitle = {Journal of Marketing Research},
    shortjournal = {Journal of Marketing Research},
    author = {Thompson, Debora V. and Hamilton, Rebecca W. and Rust, Roland T.},
    urldate = {2020-02-11},
    date = {2005-11},
    langid = {english}
}

Here is citation with three authors that works as intended:

@article{schleyer_what_2007,
    title = {What is user-centered design?},
    volume = {138},
    issn = {0002-8177},
    url = {http://www.sciencedirect.com/science/article/pii/S0002817714631640},
    doi = {10.14219/jada.archive.2007.0319},
    language = {en},
    number = {8},
    urldate = {2020-02-28},
    journal = {The Journal of the American Dental Association},
    author = {Schleyer, Titus K. L. and Thyvalikakath, Thankam P. and Hong, Jason},
    month = aug,
    year = {2007},
    pages = {1081--1082}
}
}

The only difference I can find on the author names is that Schleyer in the second citation has two middle name initials, and Jason Hong doesn't have a middle name initial. But I don't think that is the problem.

If I remove the middle name initials from the authors in the biblatex file like this:

@article{thompson_feature_2005,
    title = {Feature Fatigue: When Product Capabilities Become Too Much of a Good Thing},
    volume = {42},
    issn = {0022-2437, 1547-7193},
    url = {http://journals.sagepub.com/doi/10.1509/jmkr.2005.42.4.431},
    doi = {10.1509/jmkr.2005.42.4.431},
    pages = {431--442},
    number = {4},
    journaltitle = {Journal of Marketing Research},
    shortjournal = {Journal of Marketing Research},
    author = {Thompson, Debora and Hamilton, Rebecca and Rust, Roland},
    urldate = {2020-02-11},
    date = {2005-11},
    langid = {english}
}

I get the following by using \citet{thompson_feature_2005}: D. Thompson et al. (2005) in the text, which is also wrong.

Have anyone here experienced something similar?

EDIT:

I have created a minimal working example that is as close as I can get to the original document without sharing the whole document. It includes all the usepackage's. I also tried to mimick the use of subfiles, but I am not sure if that made any sense. Unfortunately I am not able to recreate the problem with the given example, as it works as intended.

I discovered that the citations appear as intended in another subfile-section that shares the same bibliography.

I will continue to troubleshoot, but I might have to write the citations manually.
