Greetings, @bhi.
I can provide you with some information about this issue.
If you continue to work inside of your account without fixing the errors, then this will affect your company file in the future. Don't worry. I'm here to lend a helping hand to get this problem resolved.
To fix the problem, you'll need to manually change the transaction/subject in your QuickBooks Desktop account. Note: You'll also need to make the item active again to successfully make the changes.
Below are two articles that can help you fix both of the errors that you're receiving.
Remember, I'm only a post away if you need me. Have a beautiful day!
