Priming Primer possibly making silicone tacky??

I recently purchased a new primer, I personally think it looks better then Kryon that I had been using. However I've been using mold star and the molds are still tacky where they touch the pieces. They dry slightly better without the piece in them, but this was my first molding. I'm just rather confused :dead

 

I think it actually might be the clay I'm using to make molds with. But it doesn't have sulfur in it...and I've used baby oil to smooth it....I think I'll contact smooth on...
