You either have an hybrid dock looking the same, or it isn't DL at all. In either case, the 3rd output would not be driven by DL technology and the DisplayLink Manager app doesn't interact with it/them.
I'd recommend contacting the seller/manufacturer as they may have a firmware update.
It would not be the first time that a change made in macOS (via an OS update) means the chip need an update.

I just got all three monitors working again. Reconnecting the DPLink adapter helped.

All of a sudden after upgrading I've got this sharing box in the bar.
If I click "stop sharing" the image halts.

It creeps me out.

Is there a fix for this?

Also it has gotten more laggy.
