When I update the Colorway theme options website isn't updated

Let me preface this by saying I have no real idea what I am doing. I am trying to make a new website for my parents business. WordPress seemed like a good choice even for someone like me who knows nothing about making a website. I think the problem I am having is related to the Theme I am using Colorway, but I don’t know enough to be sure. I paid for the full version of Colorway. Anyway my problem is updating stuff in WordPress and it not showing up on the site. If I update stuff on the pages it seems to update no problem. If I update stuff in the Theme options like the pictures for the slider, or text it goes all wonky. Lots of the time it doesn’t update. Other times it shows the updated photo text, but then I go back to the page and it is back the original version. It almost seems random what it decides to display. I have tried reloading the page to no avail. I tried clearing cookies/cache and that didn’t help. And the problems happen on other computers/browsers as well. I don’t know if this helps but the site I am working on is at http://www.georgehansenco.com/test/ The reason I think this is a theme issue, not a wordpress issue is that the only things affected are things updated other theme options. Either that of multiple computers I have used all have some setting wrong with their browsers. Any insight/help would be very much appreciated. Thanks in advance.
