I had the same thing happen to my 24/7 Pro a couple months ago.
Didn't affect operation, I noticed it when broken down for cleaning.
I ordered 2 extractors and it took about 1 week.
Still have one spare.
EDIT:
Make sure you compare the old extractor with the new one, mine were slightly different and I had to grind it to make it work.
Old on the left, new on the right.
I had to grind down the tab to match the old one.
The tab contacts the frame and it will not move if installed without grinding it down.
