Fixes #142

There were many solutions I could think of, but I approached the safest solution that taking into consideration the future development of that feature, I simply drew a border line around that screen to make it obvious to users that it's a screen, not a normal white space. Solutions I thought of doing:

1. I could have set the Height of the screen to auto and that should have solved the problem FOR NOW as the feature isn't already in use (from my understanding)

2. I could have made a simple code checking if the number of elements is 0, and if so it should remove that white space (screen) till the number of elements becomes at least 1, then shows the screen. But this solution will edit the code structure a bit and could be against the future plans as this screen functionality is still not 100% clear to me.
