Hi, I desperately need some advice. I'm getting the following error when I'm trying to add a new product: "Stock Item with id "537" does not exist." Of course it doesn't exist, I'm trying to add this. I went through my catalog list, and the last product ID in there ends at "530." I've never seen this before and couldn't find anyone else with this issue. What would be causing this error? How would I go about fixing it? Thanks in advance!
