the mod's greenhouse walls are all black, while the original greenhouse walls are still showing

[Veronica_Park]

i use Lnh's New Greenhouse mod and seems like there's some error. i can even walk on the black parts in greenhouse with this mod. the walls of the original greenhouse also still showing, so i can't go through the other parts of the greenhouse in this mod except using some kind like "wrap" thing

here's the SMAPI log:
