it is the first time I write in this site, and it happens that when I compile the bibliography with Bibtex I get a strange result in some references. As you can see in the following picture, in the place where the author's name should appear, it simply displays a line.
The output of the command seems to be correct, no warnings or errors:
Proceso iniciado: bibtex.exe "TAI_template"
This is BibTeX, Version 0.99d (MiKTeX 20.12)
The top-level auxiliary file: TAI_template.aux
The style file: IEEEtran.bst
Database file #1: IEEEabrv.bib
Database file #2: Ref_Act4_19_20.bib
-- IEEEtran.bst version 1.14 (2015/08/26) by Michael Shell.
-- http://www.michaelshell.org/tex/ieeetran/bibtex/
-- See the "IEEEtran_bst_HOWTO.pdf" manual for usage information.
Done.

But most puzzling of all is that basically the entries are the same, only the title changes, but reference number 54 is correct, while 55-58 are wrong.
This is ref. 54:
@Book{BrownleeML,
author = {Jason Brownlee},
editor = {Jason Brownlee},
publisher = {Jason Brownlee},
title = {{Machine Learning Mastery with Python: Understand Your Data, Create Accurate Models and Work Projects End-to-end}},
year = {2016},
edition = {First},
url = {https://books.google.es/books?id=0t-NAQAACAAJ},
}
And this is ref. 55:
@Book{BrownleeDL,
author = {Jason Brownlee},
editor = {Jason Brownlee},
publisher = {Jason Brownlee},
title = {{Deep Learning With Python. Develop Deep Learning Models on Theano and TensorFlow Using Keras}},
year = {2016},
edition = {First},
url = {https://machinelearningmastery.com/deep-learning-with-python/},
}
Could this be a bug? Or, maybe I'm doing something wrong? Nothing like this has ever happened to me. And the most similar question I could find didn't help me (here). Can anyone have any ideas?
If it helps, I am using Windows (Miktex), with TeXstudio as editor and Jabref as reference manager.
Thanks.
