Fixing the part that holds the feeder tube, may correct both problems.
I had to rotate your picture 180° to get a good look at it. It does need to be flush or the bisquettes will not properly feed, and yours is not flush. Make sure you have all three pins lined up correctly, it can only fit one way, and that should make if flush. When you reassemble you need to make sure it properly remains seated. Often when I replace the cover on the generator I will accidently unseat it. If it doesn't seat flush, then one of the three pins may be bent.
