InterCompany - cannot select Head Office Anymore

Hi

I deleted my Head office Database from the SLD in my intercompany Admin Console

Now i recreate my head office again, i cannot find Head office in my Landscape anymore

I know  by doing this will corrupt the DB if i just delete the Head office without changing to another DB

But now i have did it, not sure how to proceed

It is so difficult to find solution for intercompany,

Regards
