Deleted field still shows in customer portal

Deleted field still shows in customer portal

Hi 

I am currently customising and regularly testing/mapping new fields and having new dependencies with out Zoho Desk.

I recently added a field and mapped it to one category and it appeared in the customer portal.

I have since changed my mind about including that category and deleted the field and removed its dependency however it still appears in the customer portal. 

Is this a bug in zoho as I cannot see anywhere that i can remove it.

Many Thanks

Nicholas
