Bold post headings

Hi,
Am using site origins page builder and displaying the widget on the front page in 3 rows at http://www.ugandainvest.go.ug. I set the website to auto update and this morning the appearance of the widgets changed from this to unbold.

I am not sure what changed, the only update i noticed was the theme, of which I am using a child theme. On my local host server i updated the theme and the front page remained unchanged.

Please help
