Cannot right click --> save as

[batoceragaming]

Hi,
I installed the appimage in Batocera 38 by using github.com/uureel/batocera.pro extension

Everything runs perfect, except if I want to save an image through right click --> save as, there is no dialogue or anything. And the file is not saved or downloaded.

For download, I also noticed that I can download file normally, but when I right click --> save as, it just does not work.

Thanks for your attention
