This is by design, focusable widgets have an option, is Focusable. Widgets, like buttons, who take focus force all keys to be released. For example, this is so if you click on textbox, you're no longer sending character input to the game. Buttons default to focusable so that they work with a controller. Clicking them with the mouse will give them focus though, so just change the buttons to not be focusable and they'll stop forcing the release of the buttons.
If the user in holding down a key and then uses the mouse to click on a button in UMG it will cause the key to fire off it's released execution.
