Zerodha Margin Calculator Sorting is not proper

Was trying to get stocks with good margin. Zerodha provides https://zerodha.com/margin-calculator/Equity/ 

link with margin details. Wanted to sort the list in descending order(10x,9x,8x,....3x), but it's not sorted properly.It's showing records in word sorting order not in number sorting order... (10x,3x,4x,.....9x).

A suggession is to make the fields only numeric inestid of x factor (i.e 10 , 9 ,8 ... no 10x,9x,8x).

And change the header to MIS Multiplier(X). CNC Multiplier(X). 

We will have this fixed.
