Lead Source in Custom Views

Lead Source in Custom Views

When I create a custom view, I have to select the criteria. I am interested in viewing by using lead source. When I drop down the box, I see all the standard options as well as the lead sources that were imported from Hubspot, but I am currently importing lists with a different lead source. I made a lead source column in the csv file and gave it the name I would like it to have, but that lead source does not appear in my criteria for a custom view. How do I get a new lead source to appear there? Where do I add it? I hope this makes sense, but I am also attaching a screenshot showing what I am talking about.
