I have the same issue - the fuses seem to be just that bit to high in their sockets, for the cover to fit properly. In my case - the previous owner has fitted some velcro to hold the fuse cover in place, so now with the Classic Retrofit fuse panel fitted I just do not clip the cover in at the bottom.
Maybe there are some fuses that are not as height, or it needs a change in design in the future to accept the smaller size blade fuses. not sure it this is possible though
