multiple desktop files present - that’s expected, as Dayon! consists of two parts (Assistant and Assisted) which can be launched separately.

Names:

WARNING: The names of the repository, the AppImage and the README differ: repository 'Dayon', AppImage 'dayon', README 'Key features'

• The repository, the AppImage and the README (whichever exist) call the application by different names (see the remarks below). Please check that they all belong to the same application, and that the name of the file in data/ is the right one.

First error in the log:

FATAL: No .desktop file or multiple desktop files present

What next: once the AppImage is fixed (e.g. in a new release), comment /retest here to test it again. If it should not be in the catalog after all, close this pull request; an app that is already in the catalog can be removed by a maintainer with /remove.
