Possible Extreme Archaeology bug

The atlas passive Extreme Archaeology for expedition says:

"

Number of Explosives is one
150% increased Explosive Radius in your Maps
100% increased Explosive Placement Range in your Maps

When actually placing this one explosive, I can find no option to pick it up again/undo like in normal expedition. Is this a bug or intended? It is pretty extreme, though if intended the passive should probably say you cannot undo your placement.

I'm using the gamepad interface on PC. I don't know if that matters and if the keyboard/mouse interface works differently and allows for undo.

This issue persists in 0.2.1. There's no way to pick up your explosive with a gamepad once placed when you have the Extreme Archaeology passive.

EDIT: I figured this out. There is no onscreen display whilst using a gamepad to give you any idea how to pick it up, but it's LT+up on directional pad. Please add some onscreen display for this. I tested using mouse+keyboard and the graphic that shows the detonator with the "back arrow" graphic to undo placement is there, but nothing when using gamepad if you have the Extreme Archaeology atlas passive.
