Excel report (P&L or B&S) stores number in text in Column F (%)

Due to a formatting bug in MYOB, after exporting the report (e.g., P&L or Balance Sheet) in Excel, Column F (Variance %) always stores number in text (see pic attached). Therefore the % symbol is missing across and some further data analysis is hard to do. This issue doesn't happen to any other columns/data types. It would be good for MYOB to fix this by storing the % in number rather than text asap. Thanks
