If I enable Toolset Bootstrap selecting "Toolset should load Bootstrap 4" the button gets its settings, but they are different from the Bootstrap settings in the Customizer of my theme (Kedence).
If I select "The theme or another plugin is already loading Bootstrap 4" the <a> tag displays like a link, meaning that the btn-primary class from the Toolset Bootrap isn't applied anymore (correct), but I'd expect the same class from the theme Bootstrap to be applied, and it's not. Why ?
Thanks

When "The theme or another plugin is already loading Bootstrap 4" is selected then Toolset is relying on the theme or another plugin to have bootstrap included on your site.
If Kadence includes the Default Bootstrap CSS and JS then the button should load correctly. Given that this is the case then it's quite possible that their loading a customized version of Bootstrap.
