Media Encoder forcing DV output at 29.97 when 24P selected

Hello,

I am trying to convert an HD ProRes HQ 1080p at 23.98 to DV24P (the orchestra studio in Europe where we record score to our film is still in the DV world...) but every attempt at setting Media Encoder to output DV with 23.98 yields a 29.97 file. This creates issues with the ProTools session and out-of-sync issues.

Any ideas on why this happens and how to overcome it?
