Diacritics not exporting. GLYPHS MINI 2

Hi, I’m using glyps mini. Every informations about my version of glyphs mini told me I have the latest. I have created the diacritics (because of czech language) than I tried to export my font, but in final .otf font wasn’t diacritics I’ve done before. I tried everything I found on this forum. Please help!
Thanks
