New records didn't trigger calculation field?

Hi,
in an automatically created record I have a field with this calculation:

@Sum of xyz ?? 0

Shouldn’t it right away show at least “0” and not “–” ???
Why is this calculation field not triggered at creation time?
Is it a bug in Tape or in my JavaScript?

Looks like it could be my old reported bug (I almost forgot):
[âś… Solution] Calculation in a new created record -> Triggers record updated right away? - #2 by Tim @Tim its marked solved, but it was just a workaround. The bug seems still to exist.
