Hytera ar482g programming issue

I own an ar482g. I was under the impression due to the brochure that the radio has a 256 channel capacity.  In my cps yesterday I got to 128 and the software will not allow for any more channels.  Any help/ideas?

04/28/2020 - I have learned that the radio comes with a max of 256 channels but it splits the 256 to a max of 128 dmr and 128 analog.
