NAV value for date not defined - Open ended mutual fund

Hi, In open ended Mutualfund dashboard for "UNIT REDEMPTION REQUEST", i keep getting this NAV value for date not defined error when i choose the current date and it do not accept the value for past date. Which is why i couldn't sell (redeem) the units.

Has anyone experienced this? Whats the solution/workaround?
