Some styling seems to have changed?

Has there been some recent updates to this plugin that has caused issues with the css??

if you look at my page, the H2 headers for ‘pros’ & ‘cons’, as well as the overall percentage figure seems to be using a default font like Times or something as well as it being bigger in size.

I haven’t changed anything that would have caused this to break so that why I was womdering if it was maybe due to an update.

If not, would you know what might be causing this issue to occur?

Here’s a page s an example
