when i tried to make a sale I the same happened and when i looked with dev tools it seem you are getting a 400 API error see PM sent to you.

one other thing I did spot and that's dev tool show same multiple of the same within the name column within network tab. (I'm not sure if this maybe a issue and one of them at lest is a square item. but someone else maybe better on this.
