When I try to create a user shape in the step, ask to select the component but when I select it, the block will disapear form screen!

any solution for it?

Does it disappear after you select it, or after you select it and hit enter?

I did some search here and it is normal to be disapear.

I think that is normal. Did you try to insert it afterwards?

Ooops, should have read the post above me. Sorry.
