Yes, for sure, though it has been suggested that the system should just automatically block a second, duplicate ID like this.
Do you happen to recall the sequence of steps that resulted in these two IDs? Were they both added via the website, or could one have come from a mobile app?
It will be interesting to see if this “fixes itself” if/when someone else adds another ID. I would suggest not touching the obs until the developers can take a look, but that’s probably impossible to prevent at this point.
