Parts Fields not properly Integrated to Interface Catalog REST (parts)

Summary:

We have recently been working on implementing REST calls to the Part Master in CPQ. Unfortunately, we've had to abandon this because two of our fields will not pull into the REST Interface catalog Parts. We have attempted deleting and re-adding the fields, but this does not seem to work. What is truly odd is that we can create new fields and it adds them correctly. It seems support cannot resolve this for us so I'm turning to everyone else here. I am hoping we can utilize REST for parts and corrupted fields have to have a reason for why
