You can see what is active and inactive by looking at the color of the icons. If the test is blue, then it's active, if the text is gray, then it's inactive. The grayed out icon should remain in the list as this fixed the issue with reserved devices and not being able to delete them when the device was not longer connected.
Ya the icons seem a bit large however this maybe due to readability for some users. The old ui was a bit small.
