Steps to Reproduce :
Go to Either Resource List or Any OOB Portlet under resource planning > Filter on OBS Filter Mode > Available Options Unit Only, Unit and descendants, Unit and ancestors
Now go to Administration > Lookups > Search for OBS Unit Association mode and Filter > Now go to Values Tab > Available Options Unit only, Unit and descendants, Unit and ancestors & Unit, descendants and (this is extra)
Why these discrepancies in filter values ?
I need to put obs filter in a custom portlet only having three values same as in Resource List page
