In Settings - Cannot see were to applicate the folder settings - Attached Image to show that

I installed NTFNTF to avoid receiving notification in one of my BKP accounts, 'cause it's a duplicate of the original, and that is a missing feature in TB.

In the Pic I show what I see... and my question is:

Why I cannot manage folders as explained?

( what I'm doing wrong )

When I click on it a text cursor appear at the botton, but cannot scroll or type!
