AUX file problems.

[Murat Yildizoglu]

Dear friends, 

I am importing a LaTeX file from an old LyX file after Claude translated it to English from French (a very good translation of all text in French while preserving the LaTeX instructions). 

The LaTeX file looks good and I can typeset it manually with pdflatex. But, I want to re-edit it in LyX, and I am meeting a problem with the last version of LyX 2.4.1 and MacTeX 2024 (they are not necessarily the culprit but I have just updated them before doing these operations so they may be relevant in my problem):

When I compile my imported file, some elements get duplicated in the LaTeX file in the temp folder. In particular, I find duplicated references and bibdata and bibstyle commands in the AUX file. My LyX file has only one bibliography field at the end of the document. Latex generates warnings about these duplications but when I click « Show the output anyway », I get a readable PDF.

Do you know why compilation duplicates (in fact, triplicates) these elements in the AUX file?

Thank you very much!

Murat
