Hello Palace,
When ever you make a change to anything associated with your online site, be sure to Publish it. Yep, you will see the message about Saving the changes however, the last step is to Publish your site. Here's a few tips should you not see the changes after publishing your site. Sometimes doing an unpublish (which basically takes your site off line) and then do a Publish again works. Also ensure that before viewing your site after making any changes that you refresh your web browser by deleting it's temp files, cache, cookies, history, etc. , then close the browser, reopen it and retry viewing your site. Old browser temp files, cache, etc. can sometimes cause unexpected results. Last, if you still don't see any of your changes, it's best to contact Tech Support and ask them to "reindex" your site. That has fixed a few issues for me in the past. I'm sure there may be some other tips from some of the other Community members.
