[SOLVED] Lost the option to choose Rect Transform Anchor, why?

As you can see in the attachment, I can’t anymore choose it.
Up to some point in time I could, and now I can’t anymore.

Also, I have now another object BELOW my main UI component: CANVAS ENVIRONMENT, and I don’t know when or how or why it popped up.
I don’t know how to send it away, and I think it’s what is causing the problem.

In fact, in the backup, it’s not there. And luckily I have the backup, because I can’t see anything now.
Nothing is working on this one, and I think it’s because the transform option is gone and this new component is there.

The components SHOW in the game window, but they are not visible in the editor window.

What the hell is going on?

“SOLVED”… kind of.
I unpacked the prefab.
And then I dragged it again into a new prefab.
All solved.
What the hell is this, can anyone explain?

I discovered that the Min Max and Pivot of some objects were all reset to 0 for some reason.
I still don’t have the Rect Transform option though.

Tens of thousands of developers… and this forum seems pretty dead…

You might have more luck on Unity Answers. I have no info, I’m struggling with new UI pretty hard right now too. Thinking about going back to hard coding old-ui style.
