Hm.. Its a well-known bug, but only in the Nameless software on NamelessHosting.

You have to report it on NamelessHosting, this is the wrong place.
Maybe consider hosting the site your own using the NamelessMC software(The Same Software that NamelesssHosting And CubedCraft here uses.)
Also, if not done, report it to NamelessHosting.
