In the "Target Filters" section, have you tried selecting just the one or two fields that are being filtered from one sheet to the next rather than all fields? I'm not sure, but I think that if you limit the fields in that list then it will limit the fields that are affected when you clear the filters. You may only need to do this on the filter that goes from B to C. Let us know if that works.
Worked as it should. Thanks a lot!
