Premiere Pro shifting keyframes during an insert edit
When I do an insert edit (using the shortcut '.' key) in CC 2018, I do not see this problem.

Make sure the Source Patching on the audio tracks is selected correctly, otherwise the audio tracks won't move when you do the insert?  Apologies if this is teaching you to suck eggs - maybe a screen recording would better demo what's going wrong?
