Just a quick comment, I probably won't have time for a full reply now. The charts only show 10 most popular prefixes and suffixes, but we can limit ourselves to the first 5 and still see the effect clearly. There is no way any of the expected counts in the top left 5x5 area on any of the charts are below 1. I can add the expected values to the charts if you wish. Mathematically any cell that is both to the right and bottom from another cell has a lower expected count. If you see a value above 0 and below 1 in any cell, this means cells in the rectangle to the top/left of this cell have expected values of 1 or above (for act/exp to be below 1 and above 0 actual should be non-zero and it cannot be less than 1, so min possible expected is the reverse of the value in the cell).
