Separation into different objects fails For practice I am trying to model an object and need to duplicate and move a face (similar to the way it's done in blender guru's doughnut tutorial for the icing).
So I marked the faces I want to duplicate:

...used shift + D and then moved the duplicated face:

...and then used P and &quot;selection&quot; to make its own object out of it:

However, as you can see in the last image, the separation somehow fails. Its marked in red and I cannot do any transformation or so to the new object.
Does anybody know what's wrong here?
Thanks in advance!
As @james-t and @Christopher-Bannett wrote in the comments, edit mode needs to be exited first and then re-entered under the new object.
Thanks guys!!
