So I was able to find a way around the problem. After I created the ACTIVITYTYPE Table I would load some data using SQL Script, then I was trying to import data from a csv and I was getting the unique constraint error for that one particular txt column.
I dropped all the sql data and loaded the csv first and it worked. Then I populated the rest of the table with my sql statement and that worked. I dont know why changing this order made a difference but it did
