U2518D, daisy chain from a DA300 dock?
I am wondering if the DOCK DA300 works with the mDP function for two (2) U2518D Monitors? We had it working without the DOCK but since getting this new DOCK both monitors mirror each other instead of acting like an independent screen.
We have both setup like the image below and mst is on and mDP is also selected for this Win 10 machine.
I think the issue is the DA300 but it shouldn't be as it should just be a pass-through for the video.

The DA300 USB Type-C Mobile Adapter does not support a dual monitor daisy chain. You should consider the TB16.
Page 12 of its User's Guide states;
Multiple displays are not working
The mobile adapter only supports a single display out. You can only connect a peripheral to the HDMI port, or DisplayPort, or the VGA port at a time.

Downstream video out ports and resolutions supported
Single video out from one of the three ports:
• 1 x DisplayPort 1.4 (3840 x 2160 max) /60Hz
• 1 x HDMI 2.0 (3840 x 2160 max) /60Hz
• 1 x VGA (1920x1080 max) /60Hz
