Why can't I see my SKUs in the Admin Products Section?

Hello, I have SKUs that cant be seen in the Admin Products Section.

How do I know this?

I went to re-make an item since I did not see it. When I put the SKU in, Shopify says this SKU is already being used. When I click the link I can see the item. When I export with that SKU. I see the item. I can even go to the item on the website. But I am not able to view or edit that item.

I found that i have a lot of skus missing all from the same 2 hour period on the 27th. Attached is the export where you can view the URLs to see the item does exist.
