Planters John Deere 71 Flexplanter Plate Issue

[TexasFarmer254]

I've got a two-row JD Flexplanter that I picked up to plant some corn and watermelons with, and for those two it works like a champ in sandy land in Central Texas. But when I changed the sprockets (9 point on the drive/cover wheel and 22 point on the plate drive) and put my 72-cell sorghum plates in to plant sorghum cane seed (to make sorghum molasses), that's when I had a major malfunction. Instead of planting the seeds one at a time 4" apart, it started just sewing it rather than planting; the seed dropped more in the amount of my grain drill rather than a planter. I took the planter boxes off the units and I've apparently got two different bottoms on the planter boxes (see accompanying pictures) but the same size plates. If anyone can tell me whether or not I'm actually missing a part, the good thing is that we've got a farm equipment junk yard covering several acres not far from me and if I know what I'm looking for, or if you can describe the part or parts I need, there is a good chance I can find it/them there. Any ideas, thoughts, ideas, or criticism would be most appreciated as the John Deere dealers around here don't have anybody working around them old enough to understand what's going on with.

Ever find a solution to this?

Does that plate require a false ring? Some of the small seed plates require a false ring or a spacer plate to prevent the seed from just falling through. I have two 51 Unit Planters and the manual for it shows the use of a false ring with certain plates. The 51 manual calls for the Y2630B False Ring or H1346B Floor Plate to be used with the 2469 54 cell Maize and grain sorghum plate. What does the 71 manual say about using your 72 cell plate?
