previous formatting doesn't work when I double click and enter on SharePoint Excel

Previous formatting doesn't work when I double click and enter on SharePoint Excel.

It was normal as the original Excel. One cell follows as the content goes long.

But now it keeps minimizing even if I write two or whatever long lines on one cell. 

--------

AAA

BBB

CCC

-------- for example if these are in one cell, it should appear this way

but mine appear as below. AAA and CCC are hidden up & down

--------

BBB

--------

[#2]

I think my discussion is a bit difficult to understand. normally, cell goes automatically long and fits on my texts with "Wrap text" fuction. But now I only can see one line even there are bunch of texts on one cell.
