When you uncheck the "Hide default border" option, the garrison button (regardless of how that button is shown) appears under the default border until you hover over the garrison button. I can't tell if the whole button is elevating or if it's just a visual trick because the button is now highlighted.

Interesting! Well done spotting this, fixed version will be available soon.
