This issue happened on ZSS App/Demo and only on IE 10 and IE 11.
reproduce steps:
- open ZSS APP/Demo, it will be a blank book
- close this book by top-right button with "X" icon
	- or close by menu
 
- open any other book (e.g. upload the attached file TestFile2007.xlsx)
- the cell panel becomes chaos.
	- if switching sheet, it will become normal.
