Expedition explosives flicker when the mouse button is used as the activate button

Step to reproduce:
- (important) Bind "League Interface" button to any mouse button. In my case, I bind it to Mouse 5 (side button)
- Find any expedition encounter in maps
- Go near to the expedition encounter until you can place any explosive
- Press the "League Interface" button

Current behavior: explosive will quickly appear and then disappear before I can even place it

Correct behavior: explosive will appear in hovering stage where I can choose place to place it

Other method I have tried:
- Bind "League Interface" button to Middle mouse button, doesn't work
- Bind "League Interface" button to V, suprisingly, it work as normal
- Suspect it could be due to my mouse, buy a new mouse, test it, same result, doesn't work (-20$, sadge)
