Import tiled landscape doesnt import anything

When i hit import tiled landscape it comes up with the size of everything total, then takes a while and builds, and once everything is in the list i select it and hit load only for nothing to happen at all, in world browser window thing i can see all my tiles but they are just grayed out

When tiles are grayed out that means they are unloaded. Select them->RMB-> Load. After that imported landscape should be visible in editor viewport.
