I appreciate you for getting back to us, EllieClaireW58.

I understand how convenient it is to have the auto-match button work properly.

Since this feature only stopped after you downloaded the latest version, you can run some tests to ensure that the file is not damaged.

If the same thing happens, I'd recommend running the Verify and Rebuild tools. This tool can help you resolve the transactions that are missing in the lists.

Here's how:

1.  Go to the Window menu and select Close All.
2. Click the File menu, then choose Utilities. 
3. Tap Verify Data.
4. If you receive a specific error, go back to the Utilities and tap Verify Data. 
5. Follow the on-screen instructions.
