Just a possibility, but could your include lab cache finds setting have been turned off somehow? Yes, I realize that it still appears in your ProfileStats tab menu. I would still check settings. Use this link https://project-gc.com/Statistics/ProfileStats and under the 2nd paragraph to the left you will see Settings. Click on the arrow and scroll down until you see Misc options. Place a check in the box next to Include lab cache finds where applicable.
If there is already a check in the box, then, try to refresh the screen using Shift + Reload this page.
Decided to cut and paste into an answer since it turns out my solution worked.
