Moon Animator 2 / Edit Rig Lite: Some joints are unselectable by clicking and not in the MA2 list of rig files, but show several selectable parts

I’m trying to rig a model for animation, but after I’ve fully rigged my model, I create a new animation in MA2 with no erros, but when I look at the limbs, some of them aren’t half-transparent and has an echo-y part that is (torso and arm on the right), while other are complety normal (arm on the left):


I’m able to click to select the parts that show normally, normal (shocker), but the ones that don’t show correctly, I’m only able to select in the explorer menu in MA2, and they are perfectly fine to animate when I do so.

I’ve grouped everything in the model in folders and named every part something different, and I don’t know what else I could try and change to fix it.

Edit:
When moving the rig, doesn’t matter if it’s in MA2 or using the regular Studio building tools, the transparent equivalents to the parts I can’t select stay in the same position in workspace. Idk what this means.
