Invisible walls on the BTB maps?

What’s with the invisible walls on certain spots of the BTB maps? Specifically the ones on the round objects in front of the bases on Deadlock, and on the round part on the big base on Entombed. You can pass through them, but you can’t shoot through them. So it acts as an odd shield. Is this intentional?

I don’t think is intentional it most be a bug in forge, I remember getting a few distraction medals while standing in this objects without knowing of this invisible shield thing
