Editor Data Grid Auto-scroll Forward (a bit)

I think I've messed something up. Data grids from Editor queries are now scrolling down a page or two and not starting at the top. For small datasets, the result is always ending up at the bottom of the grid. I've tried to find a setting that I've changed, but I can't find one that controls this. Being a mere man, I am probably missing something that is right in front of me, but I claim the excuse that my eyesight is failing.

Maybe this?

Yep. That's it. Thank you so much.
