Condition Record Exists, But has not been set

Hi Experts,

I'm new here. I have an issue with a custom condition record. In a billing document, my custom condition records ZDS2 exists. When we check in Conditions>Analysis it is read "Condition record found.". Please screenshot below.

But after we release it to accounting via transaction code VF02, the custom condition record does not is missing. When we check in Conditions>Analysis it is read as "Condition record exists, but has not been set." Please see screenshot below.

Any ideas what is happening here and how to correct this issuse?

Thanks and regards,

Dale
