You may have difficulty entering a cheque against an invopice but with a different payee (director). In this situation I would skip the invoice and go directly to cheque writing (delete invoice). Cheque made out to director. 3 items on cheque.
2.director contribution (cash in) equal to expense
3.director loan reduction equal to expense
2 will be negative, resulting in a debit, 3 will be positive (credit)
