On Form 1099-R, shouldn't the amount reported in Box 5 (Employee contributions/designated Roth contributions or insurance premiums) also be reported in Box 9b?

In my situation, I took a distribution from a life insurance cash accumulation account upon retirement. My after tax contributions are reported in Box 5 of Form 1099-R. (Employee contributions/designated Roth contributions or insurance premiums). But Box 9b (Total employee contributions) reports zero. It appears that I am now being taxed on these funds which are after tax dollars.
