Event OnSelectionChanged at Combo Box doesnt fire with left mouse button

Hello to everyone ^^

Event “OnSelectionChanged” at “Combo Box” doesnt fire with left mouse button. I can click the options at drop down menu, mouse hover and click styles working but cant select an option with left mouse button and it doesnt fire OnSelectionChange event.

It only works if i use right mouse button to select.

Any idea ?

It works with the left mouse button.

Maybe you have changed some settings. Difficult to say.
