Can you let us know a page we can test on? We can gladly take a look to make sure the right Javascript and Bootstrap libraries are being included as well if there are any possible conflicts with what you have on the page.
As for the SCLogin text as the title, you can disable the "Show Title" setting in the module parameters or change the name/title of the module to something you'd prefer to show.
I hope that helps, but if you need anything else, please let us know.
Thanks,
Alex
