Folders Tracks problem

[lulukom]

Hello everyone !
I ask you to suggest a solution in the following situation:
In the Tracks window, I made several folders, inside which are instrument tracks, buses, aux, etc. And when I opened the project today, I noticed that some folders (most of them) do not open when you click on the triangles. Everything inside these folders is playing and this can be seen in the Sequences window, but you cannot open and see the contents of the folders in the Tracks window. What could be the reason ? Thank you.
PS. If you mean Track Selector, then if the Tracks tab is open, then its contents are not visible in the Track Selector window inside the folder. But if the Sequences tab is open, the Folder Content is visible in the Track Selector window.

I want to correct my request .. These problems apply only to the Tracks window, but in Sequences everything works and the folders are visible and open.

Not quite sure what your PS means, but something to try - In Preferences --> Edit Windows --> Track Selector pick always open the edit window's selector. Open the Tracks Window selector by clicking the selector icon in the lower left corner of the Tracks window, expand all the folders and make sure everything is selected/highlighted.

Thanks for the answer ! Unfortunately that doesn't work either. I want to correct my request .. These problems apply only to the Tracks window, but in Sequences everything works and the folders are visible and open.
