My sticky player pops up when I click on a track as It should, but it goes up to 1/4 of the page instead of staying at the bottom. And when I press the arrow on the right for it to go down, it goes down and disappears completely and does not pop up again when I play a track. I cannot figure out what the problem is.

This is how it looks

I haven't publiced my webside yet. The player is working fine, but it isn't placed properly on the page when it pops op 

Well I still need some things done but I'll let you know if it still is a problem at that time
