I have found merges that should take place between some of my people in GEDcom and "Private" in the profiles. I made the mistake of adding a new profile on one occasion. When I proposed the merge, the system would not allow me to merge into the lower number. I learned it will do that if the other profile manager completes the merge.
I am new to the styles and doing research so that I don't create a mess. I've found it is best to as the question on G2G when the computer won't allow the correct merge.
