"This Issuer is already registered." message

I get the message above when I try to register the LtiAdvantagePlatform (so iss=https://advantagetool.azurewebsites.net) and when I try to register the IMS Test tool (iss=https://lti-ri.imsglobal.org), but I don't have any Platforms registered with either of these names

@stopic13 Do you get a solution for this??
