Show the actual source for a linked control

I have a workflow with multiple tasks which have controls linked to other tasks. The tooltips of each linked control shows the source as ‘{{source}}’ and not the actual source. In the pic, I have 4 other tasks with identical controls. Each of those controls are linked to the controls in the pic. Some are linked multiple times. They all show the same tooltip which makes it so you cannot identify which source each is linked to.
