Adrenalin 2020 - Can't output 4k@60hz

So, I'm currently running the 19.9.2 driver with no issues whatsoever. My current link speed is 5.4gbpsx4 which is enough to do 4k@60hz with 8bpc. However, when I update to any new driver that AMD offers(Including their new 2020 edition driver) my link speed is halved to 2.7gbpsx4, which is not enough for 4k@60hz. I'm also using a Club3d DP 1.4 to HDMI 2.0 adapter which connects into a HDMI2.0 port on my Samsung TV. Does anyone know why this is happening?
EDIT: Just to add. When I update my drivers and go into Win10 display settings, I'll set the desktop resolution to 3860x2160 and then go into advanced display settings where it has the active signal/desktop resolution listed as being 4096x2160, which is obviously not what I selected.
System Config:

Mobo: ASUS sabretooth z170 mark1
BIOS ver: 113-C8800100-101
Driver: Adrenaline 2019 19.9.2(WHQL)
Memory: 32gb ddr4
OS version: Win 10 x64 18362.476
Steps to reproduce: Just installing a driver later than 19.9.2 seems to cause the issue.
Expected behavior: The monitor runs at 4k@60hz.
Actual behavior: The monitor runs at 4k@30hz with a slower link speed being displayed in AMD settings.
