Linking mute between track and sends or group track (SOLVED)

Hi guys, sorry if I ask a silly question, but I am encountering this weird behaviour: in most cases, when I have some tracks going to a group track, if I mute the group track, all tracks routed to that one mute as well; vice versa, if I have it on mute and then unmute one of the source tracks, the group track mutes as well.
However, in two cases, I don’t get this linking and it’s extremely annoying (every time I have to unmute all tracks going to the group channels)…do you have any idea why this behaviour?
Thanks for any help!

Hi,

What are these two cases, please?

Hi Martin,

thanks for replying. However, I have solved the problem, by resetting all mutes and solos I got the correct behaviour. Now everything is in order.
Cheers
