Conflicting scripts with Bootstrap

Hi, I’m having an issue with custom code in an HTML Embed. In the Embed, we have a Bootstrap CDN that is affecting the whole page. Precisely the links in the Nav Bar and Breadcrumb.

In the original design, the Nav Bar has submenus and the Breadcrumb buttons don’t have any color background. However, with the CDN, the links in the Nav Bar have a blue underline, the submenus are not showing and the Breadcrumb links have a grey background.

Do you know how can I fix this? This does not appear to be affecting the rest of the site.

Thank you!
