Should withdrawals from 403b show up as Pensions and Annuities on Form 1099-R Summary?

Only the three 403b withdrawals appear on 1040 line 4a, but all 6 are included in 1040 line 4b. The withdrawals from the 403b's all show under Pensions and Annuities instead of under Traditional IRA Distributions on Form 1099-R Summary.
