It means that a rom with the same name within a parent/clone relationship was once listed with a valid checksum and the other time it was set to "flags nodump".

Example:
Parentset got a rom: rom ( name bla crc 12345678 ...)
cloneset got a rom: rom ( name bla flags nodump ...)

so when fullmerging the set you might run into a problem. You may replace the correct rom with a possible dummy nodump one. ClrMamePro's datread will set the flags nodump one to the checksum of the valid one.
