It's not an issue per se. It's the result of there only being so much real-estate on a phone screen. You simply can't show everything all the time.
We have two leaderboards on the desktop site. Whichever one is on the left is the one that will show in vertical mobile. If you want to see the other one you have to rotate your phone.
This was a real challenge for us when implementing the visual builders on a phone....how do you show the option drop downs, the supporting "info" screens, and the updating image all at the same time. Answer: you can't. so we came up with a different solution.
