sidebar widget titles don't display

Hi,
My blog has sidebar widgets and each widget’s content is displayed perfectly fine. However, each widget’s title is hidden. I’ve looked around in the style.css html but can’t see anything that may be hiding the titles.
I deleted a few of the widgets until i figure this out but there are still some so you can see: https://www.witchslapped.org
I also made sure each widget had a title saved in the “customize” option of dashboard.
If anyone knows what could be preventing just the titles from appearing or knows where to look in the html, i would greatly appreciate any advice!
