Services not showing up on my page

Hi there,

I’m still relatively new to WordPress, so hopefully my question can easily be answered.

I’ve recently purchased the Sydney Pro theme and it looks great, but I’ve been experiencing a few difficulties adding content to my site.
Specifically, when I add a Service to my site, it doesn’t show up on the actual page. The six template items are still there, but my new content is not.

I’ve tried changing the publishing dates so that my services appear at the earliest position on the list (as explained in other forums online), but that hasn’t worked. I’ve also tried installing the Sort Order plugin so that I can manually position items on my Services list, and this hasn’t worked either. I’m starting to think that it’s a bug with the Services widget.
In contrast, adding Employees results in no such problems.

Please, could you advise me on what to do?
Take care,
Justin
