Pro Form Issue with Summing Calculation Fields


I’m trying to sum calculation fields, but it looks like final sum field is one step behind.
Am I doing something wrong or is it a bug?


Could you look at this after your vacation please? Thank you and enjoy your free week.

I want to bump something here as well.
Ive found somethign unusual on the calculation field
Jam - the settings

First option is okay

but when selecting the 2nd option

The value of the 2nd option is not displaying

PS: Calculation Field only works if modern style is not enable
