To look into your issue and possibly help you, we need the URL (link) to the webpage where the problem can be seen.
This will enable us to go through the source code, inspect CSS and look at JS errors using the browser's DevTools if necessary.
Help us help you by giving the URL of your page.
And oh, you may want to turn off minification/caching/optimization plugins/server-side etc. during this troubleshooting phase.
