Mail tab is not showing for 1 subscription

[EveMauta]

Dear all,

I have a problem with e-mail management. I have 4 subscriptions and for 3 of them I do not have problem.
For one of them, mail tab not showing. Obviously I check the checkbox "Enable mail management functions in Panel"
I've search in forum s and I do not find a similar case as mine.
How can I fix it?

Thanks
