Just wondering if this is normal behavior. All other ptfe adapters are secure but this one seems to move when filament is being extruded (BMG clone w/ fixes) https://share.icloud.com/photos/00epxdJc0_3Kupwp55sQ0G08w
You don't have the PTFE inserted all the way into the pocket. Push in the PTFE while holding the black portion out. Make sure it's all the way into the pocket above the connector.
