What would cause a folder in outliner to not be added to source control?

Essentially the topic question. I have a single folder with 4 objects inside of it that are marked for Add to source control, but the folder itself is a question mark. Other folder objects I create get marked for Add, but this one doesn’t for some reason. My team’s toolchain requires this folder in the outliner, so I’m curious if someone can help me figure out how to identify it’s location and add it to the perforce changelist manually? Forgive the tight cropping, you know how it goes with that kind of stuff…
