Activate automatic alignment

I’m new to this, but once I saved a font, suddenly on the main characters such as A, B, C etc it has created weird negative alignments. I simply want to enable automatic alignment for these glyphs. No scripts, I’m fine with going in one by one and fixing them. Anyone knows how?

Also, I’m using Glyphs Mini.

Are the components in the right order? Base first, then the marks, e.g., in an Adieresis, the A component would be first, the would be second.

Yeah, all is well… but I might have found the problem. Opened the file up in an old version of Glyphs Mini. I’ll try it tomorrow and see if that’s what caused the problem.
