List with multiple content types & forms

Question

I have a list with three content types. Each content type has its own forms.

Content Type A (Default Content Type)
Content Type B
Content Type C

My issue is that if I try to open the Edit form from within the Display form for Content Type B or Content Type C, instead of it using its respective form it tries to use the edit form for Content Type A. I have verified in SPD that each content type is pointing to its correct forms.

Answer 1

I would first check the content type definitions through the list settings to ensure that they have the correctly assigned columns for each content type. Are content type B and C children of content type A?

Answer 2

I ended up fixing this by restoring from a backup before the issue occurred.
