Photoshop Pen Tool Path Options Grayed Out

Since the upgrade to the latest 21.2 there are some issues with the pen tool options in the tool bar at the top. 

When launching PS the pentool panel is active and I can make changes to the path color and size. However, when opening a new document, the pen tool options are grayed out and the pen tool does not funcion with the color/size settings I'd previously set. 

I've included an image to show the issue. I'm running a 2010 Macbook Pro with High Sierra 10.13.6

Help would be greatly appreciated, thank you all.
