Newly created Soft body variables values are greyed out now

In the later versions when I create a Soft body object reference I could connect the blue print in the values and use the variable as needed. Now when I create them the value is greyed out and I don’t understand why I can’t use them like previously mad soft body objects.

In the pictures attached the one that is working that was created back in 4.24

The one that is not working is made in the most current version.

What changed? How do I use these now?
