tbh it just works when all those are added, mind you there are problems with M1 macs and big sur 11.2 - 11.4 fixes that. also no problem with Intel-based Macs on BigSur.
What you might try is to scrap the system extension profile and rebuilt from scratch with values from the guide and try then. From my experience with WS One, rebuilding App, Profile etc seems to do the trick (not sure why adding version doesn't work, but hey, it's not Jamf )
