Pen tool: anchor points not visible

Hi all,

since the last update I have a really strange issue with my pen tool. When I want to set anchor points they don't get visible in my work, but on the right side I can see that photshop is setting them and that they create a shape. Now when I delete my latest step (Ctlr+Z) my former anchor points get visible, but I still can't add new visible anchor points. 

I already reinstalled photoshop and reset all my setting but nothing changed.

Thanks in advance.
