Why are the greeks showing 0 when starting a new trade

[status1]

Not sure what I am doing wrong but it seems like a lot of the time when I want to place a new back trade and enter a qty at any strike all the greeks are showing 0
I have to restart ONE in order for the greeks to show up again
Not sure if this is a bug or I clicked on too many things and something got messed up

I found the problem with the greeks Apparently ONE does not show greeks for 0 DTE and when I try a trade I forget to adjust the expiration first so I just enter it in the left section not realizing that expiration is 0 DTE
