Computing preferences not listening?

Never had this happen before, but, I set the preferences for a machine to only crunch the "lasieved" & "lasievee" apps for NFS. Meaning the much smaller memory load 14e and 15e WU's. I did leave the accept work from other applications if no work is available box checked. But, now I sit down at my machine and a TON of WU's are loaded and they are ALL the 16eV5's. Just strange for it to download ONLY the WU's you didn't want unless there is absolutely no WU's for the other apps because usually when all boxes are checked there is a mixture of 14e, 15e, and 16eV5 lately. No big deal, just very strange. Accept other WU's box is now unchecked.
