What version of PDMLink are you on?
We experienced a similar issue with ProjectLink when we updated from M020 to M050 - the view "Projects I Own" was broken in M050, and showed the same comprehensive results as "Projects of My Organization". At first, the users didn't think it was a big deal and signed off on the udpate. About a month in, they realized how much they missed it...it was confirmed by PTC as a bug in M050 and addressed in M060 (which we are now running).
Not that my story helps you any, but would be curious as to what build you're running and if it is indeed related to a build. Or did this spontaneously start, sans recent update?
