On the last 3 prints I have made about 1/4 of an inch up the print there are one or two layers that bulge out of the side of the print. I don't mean it sticks out on one side and is indented on the other, it is a consistent bump out the whole way around. It happens at the same exact height on all my prints and I have no idea why it does this. Any help is appreciated. I have an 2019 ender 3 pro.

For the last 3 prints, about 1/2 of on inch up the print there is a spot where a couple layers are printed a tiny bit out from the rest of the layers. The odd thing is that goes outward the whole way around but a normal layer shift would leave an indentation on one side and a bump out on the opposite side. This is puzzling because after these couple layers it prints the rest perfectly and it goes back to printing the way it was supposed to. This leaves me with prints with a bump the whole way around. I have no idea why this is happening and was wondering if anyone had any ideas. I have a ender 3 pro from 2018.
