Has anyone come across this scenario:
I have columns in the existing phase that are exactly (no difference whatsoever) alike. In the proposed phase, I've used graphic overrides to show existing in grey. BUT... only some of the columns come up grey and the others show as new. I have checked that they are on the right phase, etc.

Anything I can do in future to make sure this doesn't happen? At the moment the only thing I can think of doing to fix this is to copy and paste the non-recalcitrant columns.
