Check box appears darker when wrapping it with a button

Check box appears darker when wrapping it with a button (almost black), This does not appear to happen when wrapped with other widgets.

1. Open the editor
2. Create a new widget blueprint
3. Add a check box to the designer tab
4. Right click > wrap with > button

Result: The check box appears darker when wrapped with a button
Expected: The button would stay relatively the same color (as it does when wrapped with other widgets)

[UMG] Why is it that every checkbox turns black if it has a button parent?
