On our left column we got a Mega Filter Pro. It is set to be a widget for mobile users, which is working fine. But today we saw that on tablets (landscape) we still see the left column, BUT its empty blank space, as you can see on the Picture-1. After that we tried to hide the column from everywhere using the bootstrap classes as you can see on Picture-2 , but its still there as a blank space. We also saw that actually the classes we input are not inserted into the main left column section (id=”left_col”), but inside nested row as shown in Picture-3.
