Touch Screen issue On platform windows

The project need use double screen ,and one is touch screen that my developed project.
But now I test use touch screen to interact UMG. It is had some issue.

UButton trigged twice event OnClicked. and keeped hover state effect. then clicked this button will right trigged.

UComboBoxString cant open,but i On Opening event was trigged.

UCheckBox changed state twice.

I Try to use
[MobileSlateUI]
bTouchFallbackToMouse=false

in DefualtEngine.ini. It not good. this configuration will let finger drag scrollbox invalid.

Is there a correct solution to this problem?

Try to run

WindowsApplication.ApplyLowLevelMouseFilter

You need to remove it if/when switching back to mouse control:

WindowsApplication.RemoveLowLevelMouseFilter
