DL crashes swapping screens and rerouting audio

[Aruku64]

I've been forcefully thrown into the muddy waters of Apple products, and the solution of choice to use multiple monitors with a 2019 MBP at my company is the Plugable USB-C 4K.

It seems to work great, but sooner or later the dock or the software crashes for a few seconds, which in itself wouldn't be the end of the world, but it has two very bad consequences:
- The contents of the screen are swapped between one of the external displays and the laptop's screen, which are the displays in the sides (the one in the center is another external display which doesn't seem to care). I'm pretty sure it is just the contents that are swapped, as the displays keep the arrangement in the preferences dialog.
- The music I'm listening to through the earphones out of the dock suddenly starts playing through the laptop's speakers, annoying my coworkers.

Is there any solution? I'm using macOS 10.15.3 and I've no idea how to see the version of the DL drivers.

Thank you!
