Hi,
I was recently trying to create a python tool in ArcGIS Pro but I don't know for what reason the tool creation window looks a bit odd!
I created a new toolbox and right clicked on toolbox and chose New -> Script. But the Options is greyed out

and I cannot add any new parameter!

I've also tried with the Default toolbox, the only difference is the Options is turned on, but I still cannot add any parameter!

Just wondering if anyone had any similar experience?!
