Filter Columns show as blank

Hi,

I’m trying to set up some queries that use filters on some columns. Like this:
select network as “network::multi-filter”
For some reason, the resulting network column shows up as blank in the results. I can filter by it, all the results are correct, and if I download the results as a spreadsheet it’s there. But it looks blank when I’m viewing it on redash. Am I doing something wrong?
