Wacom Tablet Settings

I use KDE neon user 5.14 (latest bionic) on a Dell XPS 15 9570 laptop which is equipped with a touchscreen.

If I enable gestures in system settings (see screenshot) then tap doesn't seem to work anymore in KDE apps. Eg. in dolphin tapping a folder just selects it, tapping it again and you can rename it. In non-KDE apps (tried in firefox), tapping on touchscreen works. Gestures like two finger scrolling works in all apps (KDE and non-KDE).
If in system settings  I disable then tapping on touch screen woks for both KDE and non-KDE apps.
