Ecommerce – custom html in manual gateway disabled…

Today I noticed that my payza buttons do not work on ecommerce plugin pages. When I checked the code I saw that all links look like this:
a href=\”…\”>…</a
Can I disable this function somehow? Looking in the code didn’t help, I would need days to find it.
the settings are on this page: http://my_site/wp-admin/admin.php?page=wpsc-settings&tab=gateway&updated=1

I want those buttons on product pages and in manual payment gateway page.
