Temporary AoRs are not automatically removed

Hello everyone,

due to a vacation replacement, temporary AoRs were assigned and these were not automatically removed after the specified end date. We had to remove some of them manually. What could be the reason for this?

I assign an HR employee any AoR, using a template or not, and I enter an "to date". After this "to date" I entered, the AoR is still active. If this to date is not for ending the AoR assignment, for what is the field "to date" then?
