Tiling for image widgets secretly carries over from image to box setting

When using an image widget if the user selects tiling under the image option and then changes the "Draw as" option to box. The tiling setting will remain even though "box" does not have a tiling option.

1. Open the First person project
2. Create a new widget blueprint
3. Open the Widget Blueprint
4. Add an image widget to the designer tab
5. Set the image for the image widget to the cross hair texture (should be included by default for the first person template)
6. Set the tiling option for the image to "Both"
7. Drag the image out so that you can see it is tiling
8. Change the image's "Draw as" to "box"
9. Notice that the image widget is still tiling even though the "box" option has no tiling option

Expected: The box option should have a tiling feature or the box option should not tile
Result: The box option tiles even though it does not have a tiling option
