Bug (?) "Name is not unique" in vRA 7.2 custom property dropdown

I'm running vRA 7.2 and I'm trying to create a property definition with a static dropdown list. I have some trouble creating the entries in the dropdown.

for example:

I create an entry with this name: "ABCD"

then I want to create an entry with the name "AB". If I try to save that vRA popsup an error telling me the name is not unique. But it is.

Same if I try to enter "A".

If I create "A" first and then create "ABCD" everything is fine.

This problem wasn't there in 7.1

Looks like vRA looks for a partial match instead of an exact match.
