(So, I'm just now noticing I still have contributor permissions here, but I'll be removing those from myself shortly as I don't know what darkfrei's intentions were beyond allowing me to upload a fix a few months back and it was never my intention to fully support this mod, anyway.)
I don't have SE, but I can think of 2 possible causes of this issue:
1) SE has the resource-layer assigned to both. If that's the case, then the ideal solution, I'd think, would be to remove the resource-layer from the one that can't be used for mining and allows building.
2) This mod is erroneously assigning the resource-layer to that one that allows building. Off-hand, the solutions I can think of in this situation is this mod including a per entity exclusion list, or better yet, incorporating the use of a new value on prototypes (that would only be valid during the prototype stage) for other mod users to add to their entities that should be excluded from this mod's work.
