UMG Getting true focus on widget isn't always possible

Using 4.9 custom build

Sometimes I cant seem to get real focus on the widgets when using the navigation keys such as keyboard arrows or controller. I will provide a video showcasing the problem. I edited the source so that when a widget is truly focused it will highlight.

Using the nav keys I see the focus rule however I cannot interact with the list of buttons just focus on them like as if its a preview. Hitting enter does not allow me to press the button or anything.

However, when using the tab key it does truly gain focus and you can see the button highlight, as well as allow interaction.

I narrowed it down to the SWidget class where navigation is set by using EUINavigation::Left / Right / Up / Down.

While tab key uses Previous and Next.

What can I do to make this work all the time?

Any thoughts on this?
