Incomplete Data

Mar 16 at 8:16 PM
Hello, I pulled data for a particular hashtag at three different times (one week apart) back in December. I was playing with the data yesterday and found that the data from my third week appears incomplete. In Vertices, the categories for in-degree and out-degree are blank. The rest of the data appears to be there. I don't know why this is the case when the other two datasets are fine. Has anyone ever had this happen before? Is there a way to still get this information? Thank you!

the in-degree and out-degree are metrics that NodeXL calculates, they are not pulled from Twitter. Either the calculation failed for those vertices or they are not connected to anyone (they are isolates).
