Modifying a record in a modified form

I’ve updated my form, new dropdown fields added, some dropdown fields


Pre-fixing the form, a value in the dropdown was:
FY16 - CARO - DRC - Project

Post fixing:
FY2016 - CARO - DRC - Project

I save the form, publish it, unrelease all previous versions.

Open the record with an error in it, and guess what.

I can see the old dropdown list, not the new dropdown lists.

How do I fix the broken record, if i’m getting the old form?

Why am I getting the old form, if I unpublished all of the old forms?
