Total Net Worth Updates only for the date, cannot look back at earlier dates for total net worth

Hi

I have Reckon Accounts Home and Business 2022

Recently my Total NetWorth has stopped showing the total net worth from earlier dates.

The shares update fine each day and I get that day's updated total net worth figure but that Total NetWorth figure remains the same regardless to what earleier date I go to.

Can anyone help please

Thank you, Carolyn
