Remove Access Role Profile from AP Group?

How can I remove an Access Role Profile from an AP Group in OV2500?
For example in the screenshot below I want to remove defaultWLANProfile from the selected AP Group.

defaultWLANProfile is built-in, you cannot remove it.

I don’t want to remove defaultWLANProfile but remove it from the AP Group, it is not assigned to the AP Group by default.
