macOS 11.4 - Wrong Color Profile for second external Monitor

I'm using two LG 27UL850-W monitors with usb-c.

Since I updated to macOS Big Sur 11.4 yesterday, the color profile for one monitor is always wrong, when both are plugged in. When I only using the one, which displays the wrong colors before at its own, the colors are fine again.

That means for me that there is nothing wrong with the cable or the monitor. I tried it with another macbook, which has an older macOS version (11.2.3) and it works fine.

Any others who are experiencing this problem?
