I don't know if someone in the team has this Aston CI. But if it doesn't, we can't test to see what's wrong nor give you an answer when it will be fixed.
Most probably it's a problem related to E2 and not a particular image.

For the channel list use SatChannelListEditor. It's very easy to delete all the satellites you don't need and it deletes the channels on those satellites too. Remember to save it as an E2 v4 settings.
