[rrvc12]

Expected behavior
I should be able to choose the bank account I prefer, maybe the second or third

Additional context
According to my analysis, this module adds a sale_type_id field in the account_move that is added as a dependency in the method _compute_journal_id which affects the _compute_partner_bank_id method because the journal_id is involved, the _compute_partner_bank_id always execute and place the same account
