I answered your query in some other post .
Any asset , business documents showing worth , source of funds , bank letter , bank statement , ITR etc go in "PROOF OF FUNDS"
Any document explaining things like , IELTS , property docs , previous 10th , 12th and any education , ties to country like a business or property in your name should go in " CLIENT INFORMATION " where you attach all documents alongside your LOE .
People who didn't submit documents I mentioned above , and thought no need as it doesn't say required if applying online , were REJECTED .
So please , if applying online , submit EVERYTHING .
