The time is 19:24 when I print screen.
When I check 「Use time」 box and set a previous time of today (as in the picture), the UrgencyScore changes from 1.005884350( the 「today」one) to 1.113269133(the 「18:00」 one). No due date and I didn't change any other factors (Importance/urgency slider/weekly goal etc.)
I have re-read the mlo help doc, but didn't find the answer.
I am really curious about the reason, please get back to me..
