why does Quicken change the name of my bank account

Question

All of a sudden I'm having  a problem where two of my accounts were renamed N/A.
I tried the file validation routine but that did not do anything and there were no errors reported in the log.  
I went back to previous backups, some a month old when I know the accounts were named properly but when restored Quicken renamed those two accounts N/A. 
Have seen some other threads out there about the N/A renaming. Is this some kind of recent bug. 
What's going on?

Super validate didn’t work but all the data appears to be intact so I simply renamed the accounts from N/A to a slightly different name than they were before the problem and I hope to be ok now.
  Thanks

An N/A is an absolute indicator of file corruption .... so if the initial validation didn't help, try a SuperValidation.Basically the same process as a regular validate ... but hold down the CTRL and SHIFT keys from the moment that you click "Validate and Repair" until you see the word Supervalidating.IF that doesn't help, your remaining option is to restore from backups (using successively older backup files) until you find one that doesn't exhibit the issue.  
Then Validate that file, run downloads to pickup what ever data was lost when you used the older backup (if any) and manually input any remaining, needed, data.

As I wrote, before I posted my issue, 
“I tried the file validation routine but that did not do anything and there were no errors reported in the log.”Perhaps you missed that part of the issue in my post.
