Please explain why is $40 debited at year end AND at the maturity date?

Overall that would give the company $140 (60+40+40) on the books in interest expense.

Total accrued interest expense is 100, not 140. That is whats confusing for me.

I thought at year the company debits 40 to interest expense and at maturity date the rest of the accrued interest will be debited. Please help me understand
