Created a new datafile with existing records. There were a lot of data block errors in the existing.
Found numerous discrepancies, etc. due to the bad data file and corrected all but one.
In one (not online) account there was a bad record: 5/16/2018 "Pam Sherwood" "1018143313660" The category showed as -SPLIT and will not accept any changes. I moved all records out to a new account but left that one in. I deleted it.
Ran Validate & Repair. The bad record came back. I deleted the record AND the now all but empty except for this one bad record account.
Ran Validate & Repair. The bad record comes back, but since it has no "account" Quicken is creating account ACCT_11e03. All I can do is deleted it and then it comes back with a validate.
It's also creating a category ACCT_22e04 with a date of 0/0/1900 but with nothing in it. It appears to be connected to this bad record. This started after I deleted that one account and left this bad record "homeless."
Supervalidate doesn't fix this issue either.
Since this bad record copied over to my new datafile, creating yet another new datafile, which is a real pain because of the validations (the accounts dropped off about 3 times each before stabilizing) would do the same.
I deleted all references to both date and name of this file in Quicken, yet it comes back from somewhere.
