Two Transactions on Mobile App Order?

Hello all. I made a Wendy's pickup order tonight and while adding my card to my order, it seemed to have tried to complete my order but resulted in an error. I then tried again and the order went totally through. I noticed on the bank statement I now have two transactions with different amounts. On my order history now it only is showing the one transaction that I ended up picking up. Will an app error like this correct itself within 24-48 hours? Or will my best bet be to contact support on this one?
