Tight fitting pads is a common problem with aftermarket pads. The backplates will most likely not be made by the brake manufacturer or the OE pad supplier so may not be made to the same tolerances & paint thickness is variable, particularly around the edges where a thick layer may build up.
Loose is better than tight - that's why most brakes use anti-rattle springs in one form or another.
