It's not really bug of the dashboard itself but rather a characteristic of SimHub, for certain graphic widgets and on different resolutions, you'll have to choose a target device for them to look correctly placed, I opted to place those two widgets correctly on iOS devices, knowing they wouldn't show correctly on a PC monitor.
It may be due to screen resolution differences or anything else, I can't really tell, though this shouldn't happen and designs should look equally good on any device. I've already referred this problem to SimHub's developer, but have no hope it will be solved any time soon.
There's however a simple way to solve it, manually adjust the widgets into position yourself. Unfortunately, at this moment that's the only solution.
