Ending a contract - bug - blank dialog box

[talus]

I've finished a fixed price contract with an Upworker, paid the full amount, given feedback, but the contract stayed open.  The freelancer requested that I end the contract.  I followed Upwork instructions to End Contract, but when I do, it brings up a blank dialog box (actually there is a shaded band top and bottom but no text or other graphics) - the only thing visible is the green X top right.  

   Does anyone know how to end the cotnract or report this to Upwork?

thanks,

David

Hi David,

Could you please try clearing your cache and cookies or logging in with another browser to close the contract? To learn how you can close a contract check out this Help article. If you`re still experiencing the same problem after this let me know. Thank you.

Thanks, I would have tried, but in the meantime, the freelancer ended the contract from her end.  So it is no longer open, but I was able to leave feedback (again).

Thanks for your help.
