I'm sorry to hear about the unrecognized activity! I'm happy to help.
If you click on the transaction, all of the details available for that transaction will become visible. If the details do not help you recall the purpose of the purchase and you believe that it was unauthorized activity, you can report it by following these steps. PayPal will open an investigation on the transaction, and the process will also walk you through re-securing your account to prevent any further unauthorized access.
I hope this helps!
