Coin Tax P&L report with grandfathering?

I had purchased some MF’s in October 2017 and sold in April 2019. As per the LTCG rule, the purchase NAV applicable should be MAX(NAV on buy date, NAV on 31 Jan 2018)

But as per the tax P&L report, the purchase NAV is that of buy date, not of 31 Jan 2018.

Sample transaction

Fund name : Edelweiss Arbitrage Fund - Direct Plan
Buy date : 04-Oct-2017
NAV on buy date : 12.77
NAV on 31 Jan 2018 : 13.05
Sell date : 03-Apr-2019
BUY NAV considered for sale transaction : 12.7744 , but as per the equity tax laws, 13.05 should be considered

Bumping this up. I see that grandfathering has been added for shares but not for Equity mutual funds. By when can we expect to see grandfathering considered for mutual funds also?

We are working on this, this will take sometime.
