Hi CricriLa,
It would be helpful to have more info - for example, assuming your site is live (published), can you provide a URL to the problem.
Please understand that the Community is not Tech Support but, perhaps someone may have a clue as to what is going on.
On a side note: Sometimes web browsers get cluttered with temp files, etc. and you get unexpected results - have you tried deleting your browser's cache, cookies, temp files, history, etc. After doing so, close the browser, reopen it and retrying your site. Also, trying other web browsers to a good method for troubleshooting. Just some thoughts of course.
As last option - you may want to contact Tech Support for additional assistance.
