Mysterious Window Bug on the CRJ

I just found a window in the CABINET on EVERY CRJ. Does anyone know what this is? I’m sure there is no window in here in real life. Please take it away.

Thanks!

It’s just a accidental thing they added, I don’t think it will be removed until they rework the CRJ again.

Not a priority. Thanks for the report!
