Autocomplete rule not defaulting DFF field

Hi All,

I have a requirement to default a DFF field in request a new position page using auto complete rule. An independent value set is attached with that DFF.

Value Set Screenshot:

I am passing value column(from the above screenshot) to the DFF field through ACR to default the field. But the defaulting is not working as expected.

The ACR is throwing error when the I pass the value which is not available in the value set. But is not defaulting when I pass the correct value.
