Not a bug, it's common among Chinese radios. I own three different brands and they all display - + on repeater channels in the channel mode.

One other bug(? ) that I forgot to mention is the both the + and - signs are at the top of the LCD display when a repeater is selected in channel mode. Not the expected + or -.
