Help with diacritics

Hello,

I am new to glyphs and need help on how to use diacritics. I am creating an Arabic typeface and started to fill in the diacritics glyphs. However they keep moving out of place even If the anchor points are there. I have attached a screen shot for you get a better idea. They aren’t in the right place and if I move one they all move out of place. Any suggestions?

EDIT: Don’t disable automatic alignment

Don’t disable automatic alignment. It is your friend.

Where are the anchors in the base glyphs?
