The captcha is issually triggered by code conflicts in a webpage. The best way to prevent the issue is to replace your form(s) current embedded code by the iFrame code version
Should your form contain several customizations and problem persists, then share with us the URL where the form is embedded. If the web page has other JS libraries such as jquery, then try adding a jquery noconflict declaration.
Just insert this code right after the last jquery reference prior to the form's script.
