This problem starting occurring about a month ago, and I have not seen any resolution to it.

My client is using QBDT Pro 2019 -

I was entering information a got an integrity error on an Employee, who has not worked for him in over 10 years.

It stated that his SS# was invalid (or something like that).  I clicked ok, and continued to work, and received a couple of other errors that were similar in nature.

I backed up the data file and then I verified the data and received several errors. 

I rebuilt the data, and it gave me a report of what errors it fixed and what errors it did not fix.

I then quit the software and restarted QBDT and verified the data again, and it reported no errors.

This seems to be an ongoing problem.  Occasionally when I started the software and start working I will receive some kind of integrity error but if I quit and reload the file, it seems to be ok.

How can I resolve this issue?

Thank you
