Clip/Pop noise when tracking

Whenever I’m tracking audio (such as guitar) and I can’t do the whole thing in one take, I start off with a separate audio file, record from where I left off and shorten the track so it fits the needed space. When I “combine” those two tracks though, there is a slight pop/clip/idk what it is, that happens right where the old track stops and the neck track begins and this happens with every track I arm and try to do this with. Any suggestions on how to fix this?

Are you crossfading the tracks’ overlaps and have Snap to Zero Crossings activated?

Oh, just found a video for it. Thanks for replying though!
