Dates are red even after checkbox is checked

[Saadman S_ Chowdhury]

Hi,

In general, do dates added with "//" turn red indefinitely? 

Originally it seemed like when you add a checkbox infront of the date, and you tick the checkbox, the dates turn grey - even if they were in the past.

But it seems like when you refresh the page, the past dates turn back red again - even with the checkboxes ticked.

Is this how dates generally work? Or am I doing something wrong?

(Basically, I would like to keep track of which tasks missed their due date using checkboxes and dates)
