Double-Click not recognizing

I'm trying to remap the double left-click in photoshop to act as a different shortcut.

When I try to configure double click under normal mouse, the trigger only seems to register "left-click" (as a single click). I've tried to use the double-click shortcut on my wacom tablet, I've even tried to map a btt shortcut to remap a random keyboard key as double click. None of them work in the "Click to record a mouse button:" trigger pane. Instead they all record a single left-click.

Am I doing something wrong? Are double-clicks not allowed as triggers?
