Why am I getting a check entry on 1099-R that says Box 16a state distribution amount should not be less than state tax withheld?

Box 16 is blank on my 1099-R form and has been in past years also.

Anything in box 14? If not then leave boxes 14, 15 & 16 blank, no spaces. If you have withholding in box 14 then enter the same amount as in box 2a. If box 2a is blank use the amount from box 1.
