How to save als file after modifying solo playing

[morphism]

Hello, I am using Live Suite 11
Something is strange

In an als file I am using, I have several tracks
and one of the tracks are set to "solo"
Hence, if I play, only the track which has "solo" on (which is blue color)

So I turned off that "solo" on of that track
but I cannot save the als file after that modification (because "Save Live Set" menu is disabled)

Hence, whenever I open that als file, that "solo" blue indicator is always on
so I should turn off that solo blue button each time, which is incovenient

May I ask
How can I turn off that and save that als file after that ?

Thank you

I think solo doesn’t create an undo entry. Make and unmake any other action, like muting and unmuting a random track, then save
