KNN Error Sums of Squares are very different in K Selection Error Log and Error Summary

The selection of K is based on V-fold cross-validation, with a default V of 10 folds. The Sum of Squares Error values shown in the K Selection Error Log are average errors over the V folds for each value of K, while the value shown for the Training Partition in the Error Summary table is for the entire set of cases in the Training partition. With the default V of 10, the sums of squared errors in the K Selection Error Log are thus based on about a tenth as many cases as the value for the Error Summary table. They can be translated to the scale of Error Summary table by multiplying them by V (10 in the case of the default V).
