Broken tax calculation for CRM quotes

Broken tax calculation for CRM quotes

I came across a broken tax calculation when preparing a quote.  See attached screen shot.

The calculation is as follows:
Quote total = 54350
Discount 40% of the total = 21740

Taxable total = 54350 - 21740 = 32610

however in the tax calculation popup Zoho shows 21910, which is obviously incorrect.

Please take a look and resolve this As Soon As Possible.
Sending quotes with incorrect math is a sure way to loose clients.    For everybody...
