Item categories not auto generating suggestions any more when listing..

Still having issues that the technical team says is normal when its not. When listing an item whether new or sell similar, changing the title out to the new item information should give you a new set of suggestions for the item category (at least in ebay motors) but it doesn't provide anything any more. This stopped working correctly in the middle of December, I've called so many times with no fix. I've clear the cache and cookies and tried on multiple computers and IP address, still the same. Anybody else notice this or have this issue?
