Can't change popularity

I’m trying to reset the popularity rating on our products so we can start from scratch, and when I put it to “0” and save, it says it’s saved the changes, but the number is back to what it was.



Is this a glitch, or are we not able to change the popularity number?



Thanks

Ok, so apparently you can’t reset to “0”. But you can to “1”.



Is there a way to reset all products at once?
