The height of the sound changes to a sound folder without repairability

Hi
I created folders in the initial stage of the mix
A folder for musical instruments
a folder for vocals and the like

In addition, I created a group channel and a link channel for each folder
Then I put the group and link channels into the separate folders

I saved the project and exited

After a day I went in and most of the channels were turned down in such a way that I couldn’t turn their volume back up
I couldn’t fix it

I have done this exercise several times and each time it happens again

Does anyone have an explanation and a solution for me
It’s very frustrating

Is this button turned on on any of the tracks?

Yes …a lot
The read button
Im using a lot of automations
