Can't modify potential views

Can't modify potential views

Hi,
I'm trying to modify a specific view of the potential in Zoho CRM, adding an automatic filed named "Durata ciclo vendite" in italian (I suppose that the english name should be "Sales Cycle Duration").

I can manage the operation but when I save the view the system reain in "loading" and don't complete the operation.

To make a test I tried to add another text custom field and I didn't have any problem.

This is what I did:
1. Open the view in modify:



2. Select the field to add:



3. Add the field to the view ( filed is correctly added to the view) :



4. Then I save:



5. The system present me this sceen (loading) and reamain in this situation for hours not completing the saving operation.

What can I do to correctly add this automatic field?
