Thankyou for providing an image. On the 'Quick Filter Bar' there is an icon that looks like a pin - it is the first icon. That icon is currently selected/highlighted Selecting that pin icon means 'Keep filters applied when switching folders' So it means Thunderbird is applying a filter which you used in one of your folders. Please disable it by clicking on that pin icon.

Thanks for the suggestion but seem it not work, still read have 22 email but none of it show up >.<

Please try: In image there is a small icon on far right of the column headers. It is just below the word 'Body' as shown for filter. Tooltip:Select column to display. Click on that icon and in the drop down click on 'Restore column order' to get the columns refreshed.
