Bootstrap Tabs not working when Chronofrom module is loaded

I have a strange issue when I load a simple contact form in a module position: http://www.wunschpflege.de/wohngemeinschaften

The default bootstrap-tabs in the main-content are blank. If I disable the contact-form-module, the tabs are working without a problem.

I already tried to use a different theme for chronoforms, like GCoreUI, Bootstrap3, Pure Bootstrap3 or none – all without access.

Thank you for any hint you could give…
