How to remove top small white bar (white space)

I am using a Revolution Slider on the top of my page but I can’t position it on the very top. There is still the small white bar, that is used for the Kleo Menu. I think it is the area where the small line appears when you select a menu item. I am using this code with padding top=0 but it is not working.

[vc_row content_placement="top" inner_container="no" padding_top="0" padding_bottom="0"][vc_column css=".vc_custom_1512396577895{background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}"][vc_column_text][rev_slider alias=”ieic2018submit_hero”][/vc_column_text][/vc_column][/vc_row][vc_row css_animation="bottom-to-top" text_align="center" vertical_align="yes" padding_top="25" padding_bottom="0" animation="animate-when-almost-visible"]
