Uptime robot: already configured?

Hello! Trying to configure the new uptime robot integration tonight, but can’t figure out what is wrong with it. I followed the instructions, went on the website, created and copied the key, pasted it in the integration, but i keep getting the same error: aborted, already configured… I don’t see see any new device or entity. What am I doing wrong?
Thanks for the help in advance

Fixed in 2021.9.1!
