Access setting gone

I've just upgraded my Radzen from 2.47.1 to 2.47.4. My project has AD security enabled but, when I now go into the page properties, the 'Access' dropdown is no longer displaying.

I've tried going back into the security options and doing a test (which passes) and then Saving but, no change.

Unfortunately this is a regression that we need to fix. Please install 2.47.1 again from here until we release a new version of Radzen.
