Grandstream GXP2120 and GXP1400 not in Phone Type list

I added two GXP2120 and three GXP1400 to the existing system with BT200 and GXP280. In trying to setup the endpoints I noticed that the 2120 and the 1400 were not in the list. The package from the repo is GXP2000 series firmware. How do I get the 2120 and the 1400 into the list to be selected or what should I choose?
