Alternating line colors on individual registration

We are getting alternating background colors on the lines of the individual registration page. See: www.godowntownfs.org/tickets
One is a white background and the other is either transparent or black. We are using gold text and is almost impossible to read on the white background.
Any idea what is causing this and how to correct this? Is there an option somewhere?
We created an event with two ticket types.

Hi Stephanie

This is css of twitter bootstrap which we are using as base style for our extensions (and most other Joomla extensions, I guess)

For this case, please submit a support ticket sending us super admin account of the site and the link to the page. I will have a template developer to add some custom css to get the issue sorted for you

Regards,

Tuan
