Unable to register FIDO token

[gt2847c]

On My Account page, going to the U2F FIDO Token page to register the token, the browser token prompt shows up asking to touch the token. The screen briefly shows "You successlly registered your U2F token. Return to My Account" (successfully is misspelled in the actual message), it then reloads the page and reprompts to touch your token. Not able to give the token a name as the prompt / reload cycle don't provide enough time in between to attempt it. Tried this on both Chrome 87.0.4280.88 and MS Edge (Chromium 87.0.664.57) with the same results. Using a Yubikey token.
