DP doesn’t like to have the AU and MAS versions loaded together at startup. With DP quit, move the AU versions out of the global Components folder to the desktop (or into a new folder you create inside “Plug-Ins” and name “Components (Disabled).” Then launch DP. The MAS plugs should now be available to you.
When any set of plug-ins come in both AU and MAS versions, there’s really no point at all in installing the AUs because (a) DP is very fussy about this, (b) MAS versions don’t need to be tested and examined after installation as AUs do, and (c) they’re functional duplicates just taking up drive space and serving no useful purpose.
Kind regards.
