How to add Default values in DFF

Summary:

We have multiple DFF's at Project level and want to use them for Approval configurations.

Example If Project requires additional approvers "Yes" or "No". This additional approvers is DFF with values Yes or No. We want to set default value as "No"

We tried by setting a default value type as Constant but the same is not reflceting. I tried creating a new project after creating the DFF and still no luck.

I wanted to check if i'm missing any specific configuration.
