This glitch happens all the time and is usually corrected with a day or so.

They Just Changed Views & Watches To Cover Only The Last 30 Days

Actually, they may be CHANGING views & watchers to last 30 days only;

as I have some items with over 20,000 views and other items with 10.. and I know roughly what my views used to be.

There was an update (Spring Seller 2022) that said they would be changing the way the views were calculated to reflect them more accurately.  I suppose the "old way" was basically inaccurate? 

[coolections]

Correct. Anyone who has been watching for more than 30 days is actually no longer a watcher. Most likely someone who just did not update their watch list.
