Problem with css

Hello, I want to report problems with css (chosen-container):

1)Everything is ok before filtering: https://i.imgur.com/bm5fYkT.png
2)I choose any option and a strange bar appears at the bottom (Can you turn it off? Because it changes the look) https://i.imgur.com/91uSP5N.png
3)Now everything has changed. https://i.imgur.com/Jqrg2U3.png

This problem concerns taxonomy.
