Grafana stuck on v7.4.0 on Raspberry Pi

I run the update and upgrade options on my Raspberry Pi quite often.
I notice that Grafana is updated but when I check on the Grafana page it still says V7.4.0
Even if I force and upgrade it or install the Pi reports…
"Reading state information… Done
grafana is already the newest version (8.2.2)."
I don’t really know where to go from here.
I have re-started Grafana and still get the same v7.4.0
I suspect that maybe there are 2 versions installed and I am starting the wrong version but surely updates would overwrite each other with later versions!
Any help please.
Thanks
Martin
