I did some testing with the G-EPG numbers (Had no change color button option, skin issue?).
I created 4 bouquets.
1st: cable all channels
2nd: cable FTA
3th: Freesat all channels
4th: Freesat FTA
Alternative numbering on, no use of primary bouquet.
This displays the numbers in all bouquets the correct way. no issues.
Alternative numbering off:
Channel numbers correct in all bouquets, no issues.
Choose first bouquet as main bouquet:
channel numbers in 1st bouquet ok, in second bouquet it has the numbers of the first bouquet. Also when you are in the 2nd bouquet and choose another channel using the G-EPG, suddenly you are back in the 1st bouquet. That is not wanted behavior.
The 3th and 4th bouquets has there own channel numbers.
It doesn't matter if you have alternative numbering ON or OFF, it's the same behavior.
During testing I had 1 BSOD when I choose G-EPG.
IMO that 'choose primary bouquet for numbers' is complete unnecessary and give you unwanted behavior of channel picking.
Without it, it acts like it should be.
