Have carried out all the tests and checks as mentioned in your last posting.
My H9 is up to date, the default map is the same on the H9 as in H9 control.
I changed the map on the H9 so that change no.9 should give me preset 33, I got preset 9 again, the same as yesterday when I used H9 control to change the map.
I respecfully suggest that there is a problem with my H9 and am seriously considering taking it back to the store if I fail to work around the problem.
Best wishes, Andrew.
