I am encountering a very weird problem.
I am running on Adrenalin 20.1.3 , in the global graphics settings I can enable Crossfire , but when I go to the game settings and I want to change the crossfire mode from lets say standard to 1x1 friendly ,the only option that shows up is disabled.
I ran Witcher 3 to see if crossfire is working at all , which it is.
The Problem started after I changed my Motherboard.
Windows is freshly installed.

16 GB DDR3 1600 Mushkin in Dualchannel
Roll back to 19.11.1 or earlier, see if that resolves the issue.

On AMD Adrenalin 20.1.2 this work normally, but the newest drivers are more stable (specially GTA V and 3DMark).
3 updates after and this still a issue. Please, fix it AMD.
Can confirm I'm having this problem as well, seems to be an issue with the newest versions of the software.
