Can't get 'Unit Count Type' to update

Hi,

I have an ASIN that has been suppressed for over 4 months now due to: ‘Unit Count Type’ is required but not supplied.

When the listing was originally created the unit count type was in place correctly. (Unit Count: 15, Unit Count Type: milliliter)

I have tried bulk uploads, completely deleting the product then relisting, and changing Unit Count Type: Count. Absolutely nothing works.

Details:
-Only seller/brand owner
-Using all valid values in bulk sheets
-Waited over 48 hours to relist deleted ASIN

Any tips?
