Can't Enable Network Acceleration due to client speed limit

Routers
1

I have a GL-MT6000. I'm trying to enable Network Acceleration but it says I can't because client speed limit is enabled. I don't remember setting any client speed limit and have around 300 clients. How do I disable client speed limit without going through each of my 300 connected devices to see which one may have speed limit enabled? Is there no way to disable client speed limit globally? Is the only way to do this to completely reset the router?
Thanks for any advice.

You can see that the up/down arrows are orange in color.

You can clear offline clients via the button "Delete All" to clear these speed limits, that without resetting the router.
