I translated your great plugin into Polish.
I'm using Gimp 2.10.14 (from gimp.org) on Win10 64bit and the latest version of Export layers.
Unfortunately, there is a problem with incomplete translation.
For comparison, I checked the French translation - the problem is identical (the same phrases are not translated - although they are included in the * .po and * .mo files).
What could be the reason for the problem?
