Site portfolio not updating

I am having an issue with the portfolio on my site. I have added new pictures to my photography catalog and new videos to my motion graphic catalog but they are not showing. even the widget I created that is suppose to show the new work I have uploaded shows nothing of the new pieces of work I put on the portfolio, it says the last time I added a new piece was in January.

Now I have noticed that it only shows on the home page on any computer. The only time I see the portfolio working properly is on a computer that has been into my wordpress dashboard.

I have looked at my site on all my mobile devices, on my friends computer, on my work computer and none of them show any of the new pieces I put up.
