I have an Anytone D878 and everything works fine. Updated codeplug yesterday and I noticed when I key up (going thru hotspot) on Brandmeister talk group 91 (world wide) I see "unknown" in the display. I double checked everything....and radio still functions with no symptoms....It only does this on the 91 World Wide talk group. My radio ID ok, my digital contacts up to date. Cant figure it out. Normally when transmitting, this area of the display doesnt show anything. Its receiving all the callsigns ok from the database. I googled this but nothing comes up.
