So I've been publishing my MOCs on Rebrickable and importing the parts using Stud.io's Excel files, but it always seems to miss a few parts here and there. I'm pretty sure that I'm using only parts that are available on Bricklink, since they do show up when I manually add them later.

The thing is it's really repetitive to manually find and add the missing parts everytime I make a new MOC. Does anyone know how to solve this issue so everything becomes automatic? I'd really appreciate any help.
