I'd consider it normal and in fact kind of good. It's exactly what we would expect with different polling methodologies. Different systems of collecting data and then processing that data should get different results. There should be random variance from poll to poll even within the same system.
Statistically speaking, +6 +5 and +1 across three states is a reasonably possible polling result from a reality where all three states have the same level of support.
