Created Unassigned: No Word Pair, Time series, etc. sheets [65094]

Hello, I am trying to calculate metrics for a Twitter network. Weirdly enough (maybe after the last update), the Word Pair and other sheets are no longer created.

the only sheets I have are:
- Edges
- Vertices
- Groups
- Group Vertices
- Overall Metrics
- Twitter Search Ntwrk Top Items

The worksheet is attached.

Please advise,

N.
