thanks Graham - problem evenyaully became obvious after I stopped panicing !
I had started to organise - starting from RM1 ( where all uk venues win mkts in just one BA tab ) AND moving forward to create a new profile where each uk venue win mkt is in its own tab , which I then saved as "RM4 multi"
...but now profile "RM1" is the same as "RM4 multi"

some idiot ( the one - this side the screen )
