mine works fine with 5.13 only, any other version I tried doesn't embed properly, it's up and to the left.
screenshots of the issue help to better diagnose the issue.
My issue is that it doesn't auto switch to the night skin at 20:00:00, it will stay at the day skin the whole time.
Edit: i see what you are talking about with it not displaying the files. I will fix it today (look for a new release in the first post)
