21A upgrade made Absence Types disappear from dropdown

Summary

Employees cannot schedule any time offs, maybe due to new Absence LoVs?

Hi Everyone,

With 21A Upgrade employees lost their ability to add absences to their records. On the 'Add Absence' screen the dropdown is empty, not like with 20D version.
According to this readiness material there is a new Absence LoV with 21A

Although it says we don't need to do anything to enable this feature, and I wonder if it is still connected to our issue due to our custom Absence role we use.
