Record Being Edited Removes Other Existing Data

In version 11 of PHPR, I have a simple app with 9 fields in a single Postgres database. I have not added coded items yet, just picked the database to use & selected the fields I wanted to see. The record is created fine with or without entering the Bid Price & leaving the remaining fields empty (not yet ready to complete the rest). However, when I choose to edit a record & add a Revised Bid Price, the amount currently in the Bid Price field is wiped out. The same goes for the Send Approved & Sent columns fields, it wipes out the data in the Bid Price & Revised Bid fields. PHPR is appears to be reading the entire record into memory so when the generated Save click is executed, shouldn't PHPR be writing either just the altered fields only & leaving the unaltered fields alone or writing the entire record back?
