Result of computed extrafield show differently

Hi

I created 3 integer extrafields (let’s say A, B, and C) with the formula “C = (B-A)+1”

And I am using this code in the C computed field as formula ($object->array_options [‘options_B’])-($object->array_options [‘options_A’])+1

The result in Task card page is correct. However, the result in Task list page does not.

Please see the attached image

Please advice,
Thanks!

Did you find any solution? I’m facing the same issues
