When you push an animation in nla editor you can not edit it until you make it green. if it’s not, you can only stretch it. Move it cut it… as in a video editor.
The edit mode refereed to is in the NLA. You can also get to it via its menu. (and I just learned you can also Shift-tab to edit stashed action.) You asked “Why” to me this it a great help and I would go and open the action in the action editor. And often got quite confused. The edit mode in NLA clears up a lot of issues I had with editing actions. I hope you solve yours.
There still seems to be a bug in the NLA editor. It got stuck without any track to click on.
To put it simply, there is a green track that contains dots for your keys, but there isn’t a box that you can manipulate.
In the action editor, I could only view my one action. This action couldn’t be pushed, or stashed, and I couldn’t create any new actions either.
It wasn’t a problem with editing an action in the NLA editor because I couldn’t select anything.
Since this is a bug, I was hoping to find a workaround to get past it to unblock the UI without having to recreate the entire armature.
The trick was to go in the NLA editor’s Add menu, and use Add Tracks Above Selected. I then clicked on the name of the stuck action (The green highlighted one) and it switched back to No Action. It finally unstuck itself.
It took me 2 hours of clicking around and this was the only reference to this problem online so I thought I’d add my 2 cents.
Thanks I did this and had to do an extra step, after cliking on Add Tracks Above Selected I had to click on Edit then Start Editing Stashed Action after that I just clicked on the green action and it became a normal action. I hope this helps someone
