Sharepoint to Dataset not importing historical table.

I'm attempting to import a table from sharepoint to PowerBI... but when I import it as a dataset it pulls an old version of the table. Two days ago we updated a column header and that's the version I'm seeing (the update was done prior to the upload). I uploaded the raw excel to PowerBI and I'm seeing the correct column headers. Any ideas?
