Please help it driving me crazy having to edit every cite in my database

Sounds like the issue is not due to the output style but possibly: 1) the layout of the “tagged” fields of the imported data; 2) the way the import filter is reading the “tagged” fields. How are you importing the data?  Direct export or by importing a text file?  What import filter are you using and can you provide a sample text file of the imported data to see the how the fields and corresponding data appears?
