Filter Horizontal – few problems

Hello, i have few problems with filter horizontal.
i try to put the icon of the arrows to the left but it stays for some reason on the right side and i changed the search icon color to BLACK and it stays purple. i cant understand why it happens because when i am on edit with elementor (1), i see the page as i want it to be but i see differently the page on preview mode (2)

also, when i scroll down, the filters overlapse my sticky header. (3)

i provided screen shots for the problems.
