TL;DR

Add into the tooltip that appears when you hover your mouse over "Trash Unrequested" the information that if a maximum value of a request is set to "inf.", then all items above minimum would be put into trash.

What?

The appropriate fix would be to add this to the description something in the manner of "If the maximum amount for a request is inf., then also moves items above requested amount to trash slots."

Why?

Because as a new player it is very easy to get confused about what's going on with your logistic requests if you don't know this feature. You can find more here viewtopic.php?t=130590

I maintain that the right solution is to support both behaviors, whether through an additional checkbox, a special value that can be entered, etc.
