Problem with helium 10 extension. Adds items to your cart.

Past 4 months or so, been having issues with the helium 10 extension. When I check inventory with it, it add hundreds of the items into my cart. I check another item 30 minutes later, and it adds those new items to my cart. Hundreds of items. Like it adds every ones stock on a listing into my cart. Checking to see if anyone else has this problem? I had a sub to it for the last 5 years or so, closed the account last year. This issue just started happening last 4 months.
