Unable to change USPS shipping options

[hfoxonline]

Hello,
I've recently installed USPSv5.0 shipping module on my site. I'm having some problems with it.  The first is that I can't seem to change which USPS shipping options are available.  The only things that show up in the check out are all of the priority mail options and two express mail options - no matter which options I have enabled on the back end.  I can click no for all options on the back end and the same ones keep showing up at check out in the front end. How do I fix this? Any help would be appreciated.  I have VM 1.1.9 and joomla 1.5.22.
Thanks
