New shapes eg circles are drawn behind the existing plans, so I can't see them until I click

I hope this is a simple question , I use SketchUp to draw garden plans. I don’t know what has happened - probably clicked a button somewhere but now every time I draw a new shape its drawn behind the face I am working on and it only appears on top of the face when its done. Normally when you start off drawing a rectangle or circle you see them alter their shape on top of the face and you can judge if they fit or not .
I don’t draw complex shapes or plans , usually very straightforward but I am a bit puzzled over how to correct this
thanks in advance

Can you share a screncast of this, I’ve never heard of this before.
