Question ASRock B360 PRO4 not acknowledging all cores

[undisclosed]

I just installed the ASRock B360 PRO4 LGA1151 motherboard and noticed it's only acknowledging 4 cores out of 6. I have the i5-9400f for my cpu. I've flashed the bios to the newest version available with no luck. I was wondering if anyone knows how to fix this or what the cause is in case I need to get a new board. Any input is appreciated!

Solved. Unchecked number of processors then restarted pc. All cores were detected on boot-up if anyone else has the same issue.
