Although your first screenshot does help expose the issue it doesn’t tell us the cause. The problem is you selected “Computed” instead of rules which will show us what rules are influencing the final or computed style. Can you tell me which element was selected to show that difference in screenshot 1? You can use screenshot 3 as a reference if that helps. If the element under rules doesn’t show the difference you will have to traverse the tree upward until you find the rule difference.

Hopefully that exposes the issue otherwise is it possible to let connect to your device with a temporarily different password? If so, you can email me the information and we can proceed from there in order to allow me to see the issue and possibly fix it.
