Custom boolean values for global triggers won't give the dependency block when double-clicked

So... yeah. I have a canHarvest dependency for my event (PlayerEvent.HarvestCheck), and it won't let me double-click on the "canHarvest" text, making me have to create it myself from the advanced tab. other custom dependencies (such as itemstacks, strings, numbers etc) don't seem to have this issue, it's specifically booleans.
