Is Zerodha charging extra Transaction charge on NSE?

NSE Transaction charge according to Zerodha charges section is 0.00325% (source - List of all fees, charges, and taxes on trading and investing – Zerodha). But if you give a 1 Cr trade in brokerage calculator you will see show charge as 335 Rs when it should be 325 Rs. Is thing happening in contract note also (can everyone check once)? Is there any reason this happening? Because when I checked with Dhan and Groww brokerage calculator they show proper 325 Rs charge instead of the extra 10 Rs.

I know 10 Rs doesn’t matter when you trade 1 Cr but I want to know the reason this is happening or is just that the brokerage calculator is wrong?

I am posting here because I saw this post on reddit - Reddit - Dive into anything.

Exchange mandated contract note format doesn’t have the provision to show contribution to IPFT separately. So, we’ve added NSE IPFT to exchange transaction charges and added a footnote.

Brokerage calculator also does similar calculations and the second footnote talks about the same.
