Refresh pulls new data into reports, but does not see newly created measures/KPIs

Hi PBI lovers,

I've uploaded an Excel file with a table in a spreadsheet, which is a linked table in the data model. I created one measure in the data model before I uploaded it to PowerBI.com. The data set appears, and I can create visuals, edit the table in Excel, and refresh to see the new data reflected in my reports, that's great! But, if I add a new measure or KPI to the Excel file (hosted on OneDrive for business) after the initial upload, refresh does not see those changes in the data model, only new data in the table. Anyon else experience this?
