Command Button on macro acts differnet than selecting macro from list

I don't understand why this would be a thing but I have a macro that moves data from one worksheet to various other worksheets based on country names. If I select the macro from the command ribbon (developer tab/macros/select from list) the macro works perfectly. If I use a command button with the macro assigned, or use a button_click method that calls the macro, the result is only partial. The macro doesn't complete the job but the code runs all the way through and there are no errors. I can even select the button_click method from the list and it works fine. Why would there be different behavior from a button vs. selecting from the macro list?

Sub MoveButton_Click()

Call MoveDataToWorksheet

End Sub

Dim pname As String

        wslastrow = ws.Cells(Rows.count, "a").End(xlUp).Row

To close this question out:

There's an implicit ActiveSheet in pname = Cells(i.Row, "a").Value, which means this is probably running against different sheets depending on whether you run it from the macro list or a command button.

Change to pname = rawdata.Cells(i.Row, "a").Value.
