When you have too many articulations, the labels go blank. You have to work blind at that point. We need a scroll bar so we can see all the labels.
Would it kill your workflow just to drag the divider up until the names show again? (you can always drag it back down again afterwards 
)
They disappear when there are too many. I know this sounds insane but that is intentionally how they engineered this. One can not drag it high enough on an average monitor. You would understand if you used VSL.
