@theaeon No, that's a normal case and it's handled properly. The issue would be if one of the IPs has 2 IPs in the same field separated by a white space like: "x.x.x.x y.y.y.y", or if the field is just empty or anything else that doesn't look like a proper IP address.
If you want to check the addresses more thoroughly, you can install xo-cli with npm i -g xo-cli, log into your XO with xo-cli --register <XO-Server URL> <username> <password> and then run xo-cli --list-objects --addresses type=VM \$pool=<pool ID>.
