[BUG] Disabling OSC TX/RX does not work

When I disable OSC TX and RX (and just to be really sure also for the UDP connections) I can still fire cues from an external source (QLab). I am on Eos v 3.3.5 on a Gio@5 and the connection is through the second NIC on the console.

The indicators on top of the cue list disappear as they should. The only way to disable show control is to disable Third Party OSC in settings. But I prefer to have a visual indicator for this. It used to work fine in previous releases of Eos.
