Thank you, but I already had corrected these. I wanted to understand the logic. I'll try to mix these two skins and then see if the elements are visible or not.
Another thing: in the image attached, I don't know if you can see thet the font in the audio section looks bigger than all the rest. It happens in my pc with ALL the skins, maybe because I have put big fonts in windows. But I don't think there is a solution for that.
