Knowledge management workspace

[Akshay Kumar3]

As mentioned in the image 1, when I am trying to create a new article using the OOTB knowledge base, in workspace view, I can able to see all the ootb fields in the left panel of the article form.

Similarly,  when I am trying to create a new article using the newly created knowledge base, in workspace view,

I can't see any of the ootb fields of knowledge article form as shown in image 3

I am not sure which configuration I have missed here.
