Amber shatter, can I purge it again with heat??

Hey guys I just picked up some shatter from someone who I typically dont have this problem with. So today I went to check it out and first thing I noticed is it was not glass like, more sticky than usual. When I went to dab, it crackled and tasted kind of like how band aids smell lol. Anyway, before calling the guy and making a thing out of it, I wondered if I could just heat it up and get out any butane that might still be left??? If so whats the best way to go about this? Its 3grams. So far I was just heating up the bottom of the container until its all completely melted and stirring it. Would that even help? Is this shatter garbage since it wasnt done right the first time or can it be saved?
This is how it normally looks, hard unless melted.
This is how it looks this time, its the same color i just shined light through so you could also see the little bubbles, it stays melty.

Aaaanyone? I'd really like to medicate this morning but am a bit timid with it crackling.

I guess the pictures dont really show much for viscosity or smell haha.

I took a portion and heated it up and stirred it a bunch. That part doesnt crackle anymore but still tastes...well it has a taste that it shouldnt. Either way I called the guy back just to ask what solvent he used and he was apologetic and happy to replace it, that's awesome and not something you come across often in a person. Very happy.
