Seems the import process is using the comma as a seperator... I had a Libronix 3 markup like:
offering, tithe, gift
That imported as 3 different markups like:
offering
offering, tithe
offering, tithe, gift
with only the last one only having all the markup attributes... I just manually deleted the extra entries, but not sure if some of my markups were removed in the process. (I don't think so tho.)
