Hi @Hlavtox ,

Thank you for your report, I reproduce the issue with PrestaShop version 1.7.6.9 to 8.1.2, as you can see :

Untitled_.Oct.27.2023.11_33.AM.webm

I'll add this to the backlog so it can be fixed.

Please be aware that some issues might take a very long time to be resolved.

I checked all files you mentionned and I've the same result

Thanks

Updated the list with some more files. Very weird that all of those files that were not upgraded have "install" in their path.
