how to remove the search box container at top?

How can I remove the search box on top, I have search disabled in the shortcode.
all the things that appear there are gone, but a empty box remains.

I have tried adding this to my css as that is what it is identified in inspector.
}
.mec-search-form .mec-totalcal-box {
visibility: hidden;
}

also

}
.mec-search-form .mec-totalcal-box {
visibility: hidden !important;
}

but it still remains even after adding to template css and the plugin’s css.

Any suggestions?

I am using a shortcode set to full calendar, classic, monthly, clean.
The reason I am using this one instead of regualr monthly is because regular monthly shortcode is not responsive. and overflows on mobile devices.
It also overflows on your demo as well.
