Midi Recording Question

So, just opened Cubase 10.5 and this is going to sound like I have never used Cubase. LOL But, When I set a punch for a midi punch in, the notes in the measure in front of the punch mark (left locator) are deleted. The punch works, but it takes notes from the one measure in front of the punch completely out.

Any ideas? I’m sure it’s some kind of retrospective recording setting but I am having a brain freeze and can’t figure it out.

Thanks,

Rich
