Thanks for the information. I’ve pushed out a fix for this error.
Is this on the dropdown or in the admin settings area? I have it on a site with 60 sub sites and do not see this issue and see all 60 subsites.
This was resolved in the latest update. Sorry for taking so long to resolve. I did not get an email on posts so I was unaware there was an issue. I will try and do better in the future with keeping up with issues.
