Hackintosh Won't Sleep

Specs:

• CPU: Ryzen 5 3600
• MOBO: MSI B450 Gaming Plus
• GPU: XFX RX 570 AMD
• BootLoader: OpenCore 0.5.9

I was using High Sierra as of yesterday because I was stuck with my 1080Ti. Got an AMD card today, plugged it in and did an upgrade to Catalina. Went smoothly, but now every time I try to sleep, the monitors and peripherals are disabled, but the computer is still running (fans are still spinning and my rig lights are still on). Sleeping was working perfectly before with High Sierra. Any idea what's causing this ?

Let me know if you need any more info.
