Could someone help me -whe nusing biblatex with the apa style and the biber backend,journal names only are not line-wraped according to my document setting (see print screen below):
\usepackage[style=apa,sortcites=true,sorting=nyt,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{references.bib}
\printbibliography
Could you help me? It is very much appreciated. Thanks.

\usepackage{ulem}in your preamble, if so then change that into\usepackage[normalem]{ulem}. Or put\normalembefore\begin{document}. – Marijn Nov 09 '23 at 13:46
