Can't see vector paths

Hi,

I'm quite new in the field of Adobe Animate and have quite of a simple question. When I import the vector graphics from the Animate CC Lib, the object is divided to symbols but I can't figure out how to show the trace vectors. The Ctrl+; , ctrl+u, ctrl + h don't seem to work. The Show Edges and Show Bounding Box are turned on.
Might the problem be caused because I have a trial version of Adobe Cloud ?
