How to make the Number Card display more precise decimals?

I have submitted several payment entries, and the total payment amount is 3354.45. However, the Number Card named “TOTAL OUTGOING PAYMENT” under the Accounting section only displays 3354.00. I have tried multiple times and found that the Number Card rounds the value and discards the decimal part. How can I configure it to show the exact amount? (I have already disabled rounding in the global settings.)
