Persistent tackiness and bubbles

Hey there! I am super new at using resin, but recently began to experience with dice making. I’m in a bit of a trial and error phase and trying to find what works!
I’m having some problems that I keep experiencing everything I take my resin out of the molds.
-The resin is always slightly tacky
-lots of tiny tiny bubbles
-sticking to molds so much I’m breaking off silicone taking the resin out

What I’ve tried to do,
-heating up resin and molds before pour
-pouring slowly, mixing slowly

I’m going to try using demolding spray on my next pour, hoping to lose that tacky feel. But I’m wondering if it’s the resin/mold itself? I left some resin in my last pour in a cup that that came out perfectly- no bubbles and perfect smooth.

Currently using:
– Smooth on oomoo 30
– Amazing clear cast

Any advice would be amazing! Thank you!
