Yeah I actually made a mistake. The Ultimatrix was placed in storage because it was unstable and the Evolutionary function wasn't actually implemented in it and Azmuth doesn't intend to. He placed it in security storage and was stolen by Albedo, stabilized it, and added the evolutionary function. Azmuth was probably already working on the New Omnitrix that was given at the end of UA after placing the Ultimatrix in storage.

It's like what he does, he also placed the Unitrix on storage, either when he started making the omnitrix or when he finished making the omnitrix. The Ascalon and Ultimatrix is probably in storage. Probably waiting to be stolen by some villian or they may have been destroyed or deactivated by Azmuth before placing it in storage.
