"OLE DB or ODBC error" error when refreshing PowerBI Reports

[dmccrickard323]

When I try to refresh any of the PowerBI Reports (such as Cost Summary) from my Storage Account, the below error appears against the Costs and Prices tables:

Costs
OLE DB or ODBC error: Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH)).

Prices
OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E.
