[chirp_users] CRT Micron Frequency Issue

[Paul G7BHE]

Hi everyone
I have just bought an expanded CRT Micron UV. 
It has frequency coverage of 136-174 and 400-490. 
CHIRP is not allowing me to enter frequencies outside of 144-146 & 430-440. 
Has anyone else encountered this? Is it a CHIRP issue perhaps?
I am able to enter the frequencies manually onto the radio and using the OEM software. But frankly that is a really bad program. 
Thanks
