My clients website is not properly updating In web browser

Hi,
A website I have been working on for a client, has not be properly updating changes in the web browser. I did some edits weeks ago, and just logged on today and noticed the edits I did weeks ago, have not shown up. When I type the client’s url into the web browser. Now if I go to wordpress dashboard and view it from there, it updates fine. The old website has the title header and picture of a butterfly showing twice, due to me trying to figure out how to put a pic inside a row and got help from the support forums a month back (Needed to use a grid row. Thank you for the support) but now my clients website is not propagating and it’s been weeks. How do I remedy this?
