Can not remove settings from a .mobileconfig file

We are playing with iPads within our company. So, I used the ICU to create separate config files for our VPN and our Exchange 2007 settings. In both config files I set the Security to "Always" to allow users to remove the profile. When we do this for real, I probably won't but since I am testing it with my device, I'd like to be able to manually remove the profile without using the ICU. No matter what I select for Security, the Delete button is missing from both the VPN setting and Mail account settings. There's a message instead that reads, "These settings are installed by the profile 'Exchange Test'" I've tried a direct install via USB from the ICU and emailing the file to myself with the same results. The profiles work, I just can't remove them.
