I'm working with a very large dashboard and thus cannot share it, but I'll do my best to describe the problem. I am attempting to extract data in order to share this dashboard it is a map that has the data filtered by cancer type. The list of cancers in the filter is about 28 different types when the source is live. When I extract the data 9 of them vanish. I keep checking the extract and all are selected in the extract so I cannot determine why they are disappearing from the filter list. Thoughts?
It sounds like you have a Filter Condition on the extract or you've limited your extract to a certain number of rows or similar. Remove the extract and recreate it from scratch ensuring the settings are correct.
