Syncplay version 1.6.4a
macOS: 10.14.6
The menu for "Add file(s) to bottom of playlist" is stuck in German and will sometime pop up on its own. System's language setting is English(US) and this is the only menu that's in German. The menu will sometimes pop if there's a few files in the playlist, but no files will appear. At least, I haven't noticed it when it's empty. If I open the menu normally, a second menu will appear on top of the glitched on and both ill disappear.
Neither problem is effecting functionality.
Here's a screen grab of the language issue. Next time I see the menu that's glitched, I'll screen grab that.
