Incorrect Display of DMR ID/Talkgroup

[kb5udf]

Hi all, I have a new Retevis RT84. I currently have the 4 frequencies of a hytera XPT system programmed into the radio under 8 channels (2 channels per frequency to accomodate time slot one and two.). I put the radio in scan mode, and I have a grouplist which includes the groups I want to monitor. Problem is, the radio does not display for example "Contact 4" or "Contact 1" (as I have it labeled), but isntead for talkgroup 10 it displays b a number such as 2097162. The radio id is correct confirmed by monitoring with an SDR. . Other talkgroups do something similar, a number, which is not what I have things labeled as, but the number/talkgroup is consistent. I know what the talkgroups are because I've monitored with an SDR.
When I monitor a ham repeater without a group list put in, (that is just one talkgroup),the contact/talkgroup text displays just fine.

What am I doing wrong?

Thanks in advance

I'll add that I've discovered that the following contacts/talkgroups are displayed as follows:
Talkgroup/Contact Display
4 2097156
5 2097157
10 2097162

So basically it adds 20,9752 to whatever the talkgroup is and displays that. I'm starting to suspect a firmware bug.

No, it's high by 0x200000 (2,097,152) because XPT doesn't use 24 bit IDs and your radio knows nothing about XPT.

Thanks for the correction and the info.
