[Dx4win] Help with Export

HiI'm trying to create an .adif file so I can upload my log to LoTW. When I try to do that the only QSO's that end up in the .adif file are the ones dated in the year 2000 and later. All of my earlier QSO's are not there. I've tried cancel filter but that doesn't seem to work, either.
