sysmond using 100% CPU usage, but only while on the Memory tab

I used to have no issues with this, but all of a sudden sysmond is using 100% CPU while I have Activity Monitor set to the Memory tab. sysmond runs normally while in any other tab (CPU, Energy, Disk, Network). The problem only occurs on the Memory tab. Turning down the update interval does nothing. I've already restarted and had no other apps open except AM but nothing changes. It still uses 100% while I'm on the memory page. I am using macOS 10.14.6, on a MacBook Pro.

Solution 1:

I've fixed it. I had shared memory and private memory both checked. Enabling either one seems to cause sysmond to spike in CPU usage, and having neither checked returns sysmond back to its usual state. Odd.
