Attribute date is not available under table column for data type date while creating Receipt DFF

We want to create a DFF for date under flexifiled code AR_CASH_RECEIPTS. When we select data type as date, the table column is blank. We have uptill now used 14 attributes. When we select data type as character, than table column is automatically getting populated with ATTRIBUTE 15 but when we select data type as date, nothing gets populates in table column even after using search function. We tried using default value set as suggested / answered to one the quetion in this community but still it did't work.
