Unworkable Mask

Not sure how to fix or address this. I'd like to add multiple layers to unwalkable.
Doesn't seem to work, I thought the checking multiple in the editor drop down would work.

Looked a bit deeper and I guess because my 'water' layer is under everything it makes the whole area "unwalkable" ??

Ok I cheated and made any grid that was value over 100 unwalkable. Cheap but it works.
