How do I remove an attribute from a form field?

[AllenTschumper]

Couple questions.

#1 - I added an attribute on the Description field within the form for our Freight Internal Case view.  I added "Knowledge Search" so I was able to then be able to search the knowledge base for any related articles off of what is in the description.  Was working...then I wanted to see how the Knowledge Custom attribute would work and it then caused the search to not be able to happen at all.  No big deal...was worth a try.  But now I cannot remove the attribute.  I am an Admin and should have the ability to do so.  I see you can flip the value to False, however, that is to no avail...doesn't do anything for me.  

So, anyone know how the attribute can be removed?

#2 - I wanted to just get the Related Context Search or Contextual Results to appear and work within our cases as well...however I cannot seem to get that to work.  I remember doing this ages and ages ago in our old instance and have now forgotten how it is done 🙂

Any help is much welcomed.

Thank you.
