you should dissamble the bolt,there is something with bolt stop,same as probably could be damaged sear part when not holding the hammer piece in secured position,most real the extractor doesnt work corectly,as he should held the bolt head in opened position.all parts would be good dissasemble and look for details.

Is it the extractor that holds the firing pin back?

There could be problem with safety as not correct bringing the hammer back into loaded position,or there is problem with sear extractor and trigger assembly, weak spring or something else? The bolt moving back should be stopped on triger sear position, only by pushing the trigger forward direction should be movable bolt back out of receiver, i would change the trigger sear spring or look at trigger upper part details.
Extractor in bolt holds the bolt head in opened position when pulling out the bolt from receiver bridge and the bolt should be remains in opened forward position, not as here in the first video that the bolt is closing head to body of bolt. That means the notches inside of bolt on extractor are damaged already.

Sear-ejector assembly, perhaps? Disassemble it and clean it up very well, make sure the sear and cocking piece geometry is correct and that it fully engages. It appears that after the safety pulls back the cocking piece the sear drops down. With a normal string and non-binding sear this shouldn't happen.

Yes sear ejector part under receiver should be inspected.

Safety could be replaced or look at the nuts of safety that engage into bolt, same as the ejector sear complet should be cleaned look at the inner spring, clean from old vaseline and dirt. bulgarian refurbishment has a lot of vaseline that could be dryed in slots already. there could be some damage on the sear too, that is not clean or has some chip, that will not return to spaned position.
