Summary:
The kingfish driver operates by requesting data in 64-word "Network blocks". Each data request is for a single block e.g. 1-64 or 65-128 etc. When defining an array which crosses network register block boundaries, it is found that only the values in the first network block are displayed correctly. For example, if an array #R61 to #R71 is defined, then only #R61-#R64 will be displayed correctly. 

Solution:
Do not define an array which crosses network register block boundaries. Note also that the maximum array size that can be defined for the KINGFISH driver is 64 words and this can only be one complete network block.
