Hey @rebeccasmithhhh, welcome to the Seller Community! Congrats on your first post!
At the moment, there isn't a way to bulk edit items directly in the Square Dashboard. I'll pass your comment over to our product team for them to take into consideration.
Usually, when items are created, a location is automatically assigned to them unless otherwise specified. Do you have multiple locations set up on the account? Is it possible that you may have logged in to a second location that has fewer items assigned to it? If at all possible, can you send over a screenshot of what the screen looks like at the moment?
The more information you can provide, the better I'll be at resolving the issue.
Thanks!
