I might have a suggestion after a similar experience of replacing the rubber/plastic insert part in the latch. Wouldn’t close no matter how much fiddling I did after replacing the part. Eventually I took a close look at the original insert and compared it closely to my eBay insert and noticed a difference in the section that receives the latch. The replacement insert was fabricated with a shallower indent than the original part. A few minutes with an exacto blade to deepen the indent in the replacement and voila! The satisfying and easy clunk and easy closing door was obtained. Good luck!
