Did you configure the WiFI parameters as part of the IT Policy (IT Policy > WLAN group), or did you create a WLAN configuration and assign that configuration to the user(s)?
Sounds like you just used IT Policy, which is pretty much garbage.
I would recommend that you use the WLAN Configurations and push those to your users instead.
The WLAN configuration name will display on the device, and you can customize it to whatever you'd like it to be.
