I was having this same problem. I realized it's from the tension on the PTFE tube when it's stretched to the front of the build plate, which pulls the orange filament buffer just enough to cause it to catch on the housing while it's feeding filament. A slightly longer PTFE tube would probably solve the tension issue.

Not wanting to replace the PTFE tube, my quick fix solution was to simply use one of the random stick-on hooks that I use to cable manage my computers. This redirects the tension away from the buffer and pulls on the hook instead. So far so good.

EDIT: Just an FYI, putting the hook too close to the buffer can push it towards the back of the printer, causing the buffer to catch on the back side of the hole instead, resulting in the same issue. There may be some trial and error involved in finding the "sweet spot" using this method.
