Field getting updated on 'Update' button but not on 'Save'

[Vedant]

Hi All,
We have a section on our form which contains some variables from our Record Producer. When i am trying to update the 'description' field in this variable section and clicking on 'Save' from Form Context menu the 'description' field on our form is not getting updated. While if i do the same and click on 'Update' button the 'description' field is getting updated.
Note: We have a business rule that is responsible to do this sync. It is working for all other variables present in the variable section but not just for 'description' Variable.
Attaching screenshot for better understanding.
Any help is appreciated.
Thanks

On clicking Save it doesn't update the 'Description' field on the form above.Updating Description value again in the variable section and clicking on UpdateThis updates the Description fields as well
