problems with Navxt plugin

Could you please guide me how to fix the problem i see in my site. When i click in ‘lista de deseados’ o ‘foros’ the crumb is messed up.
when i go to page.php and comment out this part bcn_display(); the crumbs are gone from everywhere but this two links… I don’t know what is happening.
my site is sevatodo.com. I’m using latest versions of both wp and pluging.
I’ve had the problem from very first time i installed the plugin. I’ve go now a new update but same problem. I went to sitemile.com to copy the configurations from their theme admin but i still see the same problem.
thank you
