Accents/Diacritics Issue

Good day Everyone, I am currently having an issue with my accents not properly aligning with my letters, certain letters are also absent even when i have designed them.

I used anchors to set them up and have tried aligning them but that doesn’t seem to work

Does anyone know how i can work it out?

Do you have anchors in the base and accent glyphs? Have a look at this page: Diacritics | Glyphs
