Issue with a mod of mine - Tree Sapling Redux Pre-Oiled

[GTrista]

Hello,

I am asking for help. As a modder with little experience I had chosen to port the mod "Tree Sapling (Redux)" from FuryoftheStars in the Mod Portal: https://mods.factorio.com/mod/TreeSapli ... rom=search

And managed to port this mod with moderate success into Factorio 2.0:
https://mods.factorio.com/mod/TreeSapli ... x-PreOiled

While the mod is working as intended so far, now I have an annoying issue that one of the entities this mod provides.
The Planting Box is just invisible. I have checked around with pictures and animations but I have no clue why it shows as invisible despite it having a distinct entity picture to use.

If someone more knowledgeable is interested, please check upon those mods if I made any mistakes in porting this mod into Factorio 2.0 or not.

Any help would be appreciated.
