I fixed it now for Minecraft 1.18 in version 1.1.7a.

Thank you for reporting the issue and thanks you @madjoe1976 for more details!

sorry.. its not fixed... now you cant enable it anymore @chunkloader mapinterface or. do we have to craft new one?
or it the inface (map) shows wired behavouir.. you cant enable or dsable part example 3x3 shos all not loaded.. cantt enable.. after server rebot it shows some enabled

update... os overall it seems now to work.. that is only the interface issue.. i figured out.. if i deply a fresh loader.. and try to activate on the map, the map does not react but after server restart the map shoes the activated ones where i cklicked befor.. so its an interface issue.. befor the update the interface works fine but after server restart the map shoes all chunks not loaded..

so something with the map interface seems to be broken now.. hope you got me.. my english is not the best ;-)
