one list item, wrong value, two graphs

The Brymen BM86x meters provide multiple values in several displays. The
brymen-bm86x driver provides the P1 and P2 channels. The sigrok-meter
application "detects" the wrong number of channels, and associates
values with the wrong channel. The image illustrates this:

- There are two graphs, for voltage and frequency -- which is OK.
- There is one(!) channel in the list, and it shows frequency -- while
  there should be two channels, P1 for voltage and P2 for frequency.

Compare this to the command line tools' output:

$ sigrok-cli -d brymen-bm86x --scan
The following devices were found:
brymen-bm86x - Brymen BM869 with 2 channels: P1 P2

$ sigrok-cli -d brymen-bm86x --samples 2
P1: 1.0012 V AC AUTO
P2: 49.99 Hz
P1: 1.0012 V AC AUTO
P2: 49.99 Hz
