Confirm Selection button not working in Qlik Sense Container List Boxes

[Molly-S]

When using List Boxes in my container within my Qlik Cloud app, I must hit 'enter' on my keyboard to make the selection using the search bar. If I hit the check mark/confirm selections button, it closes the List Box drop down. 

I know I can manually click values in the drop down, but should be able to use the search bar and the check mark/confirm selections button.

Picture included. 

Any thoughts?
