Hello there, @dbullough.

I've checked that you've posted the same question twice and my colleague Candice C has already added an answer. If you haven't notified with the new response, here's the link: https://quickbooks.intuit.com/learn-support/en-us/reports-and-accounting/suddenly-cannot-add-or-save...

I'll be around if you need a hand on this. Keep me posted if you have any further questions.
