Scrapping Table Returns 'Null' Sets

So I'm trying to scrap this website for NFL rosters. Created a sitemap as such: {"_id":"lineupRosters","startUrl":["https://www.lineups.com/nfl/depth-charts"],"selectors":[{"id":"Team","multiple":true,"parentSelectors":["_root"],"selector":".logo-name a.link-black-underline","type":"SelectorLink"},{"id":"Roster","multiple":false,"parentSelectors":["Team"],"selector":"div:nth-of-type(4) a.page-heading-nav-btn","type":"SelectorLink"},{"columns":[{"extract":true,"header":"Pos","name":"Pos"},{"extract":true,"header":"Name","name":"Name"},{"extract":true,"header":"No.","name":"Number"},{"extract":true,"header":"Rating","name":"Rating"},{"extract":true,"header":"Ranking","name":"Ranking"},{"extract":true,"header":"Height","name":"Height"},{"extract":true,"header":"Weight","name":"Weight"},{"extract":true,"header":"Age","name":"Age"},{"extract":true,"header":"Birthday","name":"Birthday"},{"extract":true,"header":"Exp.","name":"Exp"},{"extract":true,"header":"Drafted","name":"Drafted"},{"extract":true,"header":"Draft Round","name":"Draft Round"},{"extract":true,"header":"Draft Pick","name":"Draft Pick"},{"extract":true,"header":"College","name":"College"}],"id":"Table","multiple":true,"parentSelectors":["Roster"],"selector":"table","tableDataRowSelector":"tr.t-content","tableHeaderRowSelector":"tr.t-sub-header","type":"SelectorTable"}]}

All it has to do is grab a table. The problem is it only grabs the results that can be visible within the viewing screen.


If I actively scroll, it grabs the entire table. What's wrong here?
