When restart server claims disappear

[Wqttzicue]

If i claim some chunk, and then restart server the claimed chunk dont save anywhere.

[Wqttzicue]

The claim is actually listed, and i even can teleport to it, but if i try to execute /claim settings in claim as owner, i tells that this is unclaimed area

[Wqttzicue]

btw this error appears if i execute /claim setting
