Show card label only if exists in Jira old project (in cards layout)

[Idan Edry]

I need help and want to show spesific field (for example: due date) in a card layout only if it was defined, currently it shows "None" if not defined.

Hi Idan - Welcome to the Community!

You can not make a field show up or not show on the card layout based on any criteria. It will always be there or not, regardless of if it has a value in it. 

If you desire that feature, you should open up a support ticket with Atlassian.  :-)
