I submitted a support request on this as well, but it recommends reaching out here too.
In my Legacy 22.214.171.124 database, I use date ranges often. The RootsMagic Legacy import lost the ranges, which is a big loss of information. I need to have the ranges preserved.
For example, in Legacy I have John birth date of 6 Oct 1818 - 5 Oct 1819. However, after the import in RM7 I only have the birth date as 6 Oct 1818. RM7 lost key information, so I think this should be a high priority bug.
