Multitouch issue on mobile platform

I am making a 2D sidescroller game.
I have created UMG for controlling player on mobile platform but I am having an issue with multiple touch.

I want my player to move and and fire bullets at the point where the user has touch the screen, simultaneously. The movement and jump buttons in UMG works fine and I can press these buttons at the same time but I cannot fire bullets while pressing any UMG button.

My player only fires bullets when no UMG button is pressed.

Can anyone help me with this?

hmmm…
Go to each of the buttons and disable this function.

I have disabled is Focusable on all buttons but the problem still remains
