Not getting an update after removing public beta of Mac OS

I installed public beta profile and the last version that I installed before removing beta profile about 2 months back is 10.15 Beta (19A573a). In these two months I have not received any single software update. I doubt it that there has not been any commercial software updates released by Apple after that beta, in fact 10.15.2 is currently available for public.

Why is this a case? Can somebody help me resolving this?
