Numbers and signs are missing after export into .otf file

After exporting the.glyphs into .otf, numbers and signs are missing but are containing in the glyphs file.
What is my mistake? sorry for annoying - im new into all of this…

This is most likely a font cache problem: https://www.glyphsapp.com/tutorials/eliminating-font-cache-problems

I just followed the instructions, but my glyphs are still missing…

Could also be an interpolation problem. Are your Weight, Width, and Custom values the same for both master and instance?
