Second Monitor won't recognize every time

Hello,

I have a problem with my DL-6950 dual HDMI 4k60 to USB-C adapter.
In the most cases if I start my Mac M1 13" ProBook or my Windows PC the second Display will not recognized. If I switch the refresh rate from 60 to 24 and back again, the display works.

In very rare cases it works on the first try. But I can't find a solid way for this.

Environment:

- two 27" 4k60Hz LG Monitors with hdmi
- 13" macbook pro m1
- intel 13900HK Desktop PC
- the DL-6950 dual Hdmi adapter is behind a caldigit ts4

Any ideas or experiences here to solve or confirm this issue?

Best regards
Michel

PS: in the os and display link software the display is showed up and I can't move the windows to the screen.
