Hello! Recently noticed some rattling inside my cabinet and it appears a plastic white piece had fallen off. No idea what it is and how it impacts the cab. I'm wondering if anyone has had experience with this. The cab appears to be working fine, but I don't want to cause further damage if possible. What is this piece? How does it impact the cab? Also, the remaining part on the electronics appears to be disconnected on the left side and connected on the right.
