That’s because the dock in question is a plain USB-C dock - not a Thunderbolt one.
Macs do not support DisplayPort MST, so they will only drive one display over a plain USB-C dock. The typical symptoms of driving two, in a MST way, are that the Mac only detects one of them, and that they seem to mirror each other because the hub or dock feeds them both copies of a single video signal.
Macs that support driving two or more displays over USB-C or Thunderbolt can typically drive up to two UHD 4K displays, running at 60 Hz, off a single Thunderbolt hub, dock, or dual-display adapter.

I ran into a similar issue, and I found that using a USB-C to DisplayPort cable solved it. It stopped the dual mirror and fixed everything!-MacBook Air M4
