Intercompany Journal Entry not working

I want to create a journal entry from different company accounts but its says “Account Cash in Bank - BDO - GP-CC does not belong to Company TEST Garcia’s Pawnshop” but I have already followed what the docs instruction in here Inter Company Journal Entry, I already checked the “Inter Company Account” checkbox, have two different companies, but it still won’t work. I still cannot fetch the accounts in other companies. Have I missed something?

This is what it looks like in my instance.
