In my specific problem, is I can't select any layer, but the layer are not locked. I don't know if is for there are symbols, or what's the problem. 

Originally I think was the symbol orange gradient. But now I don't  know if is the symbol gradient or something else.

You are working inside the symbol layer. You need to create objects outside of it.

But, I don't have any symbol created.

On your video, the root symbol's layer is hidden above. Scroll up your layers panel.

Layer (Master A) not visible.

You seem to be in Publisher, where the orange bar indicates that the contents came from a Master Page.

They will in some situations act like they are locked, and if you need to make certain changes to them you need to right-click on the Master Page layer and choose Edit Detached.

Walt thank you very much. It's curious, because don't appear that option.  I search in web and I see other people share images with that option, in my case I don't have this option

Thank for the help. I found de option, is in the page, in the master layer, I right clic and appear the option Edit Detached, in another simple layer don't appear the option. Thank you very much

I think choosing the same (orange) color to indicate completely different things (Symbol and Master Page) was a mistake.

Master Pages are implemented by Symbols, but I agree that a different colour would help distinguish them.

I don't think the method of implementation is very interesting for users. For example, the use of Symbols on Master Pages is really successful.

Some people prefer knowledge to ignorance, so speak for yourself. I provided an explanation for the colour being the same. I agreed with you that a different colour would be beneficial.
