Recurring payments won't load certain items

Here is an example of their previous monthly bill.

You can see the item they're charged for is clearly titled "Exchange mail"

So, I go to create their new invoice and try to choose the item and I get this...

As you can see, the dropdown list never populates with the option for Exchange Mail.

In fact, there are Two items in my list that should pop up.

Here's my item list:

Either of those items should appear.

And at the risk of repeating myself - I've been setting these accounts up for years now. This isn't something new I'm doing. It's something I've been doing for a long time that stopped working today.

Various others items also won't show up in the list.

It doesn't matter if the item is a subitem of another. I've tried editing sub-master relationships with no luck.

I'm totally open to ideas because I'm stuck right now without being able to update monthly billing.

Please advise.

I can see how difficult this has been, @TommyJordan. So I'm here to take this opportunity to ensure you'll be able to create recurring invoices in QuickBooks Desktop (QBDT). 

First of all, I'd like to thank you for choosing QuickBooks as your accounting partner for a long time. To express my gratitude, I'll make sure we can fix this issue.

Also, I appreciate you adding detailed information as well as screenshots in your post. This serves as an awesome reference for me to provide the recommended fixes for your concern.

To start the troubleshooting steps, let's use the Re-sort List feature of QBDT to resolve the odd behavior you encounter in your Item lists. This process will return the default order of your list. Here's how:

1. Open your QBDT program and go to the Lists menu.
2. From there, choose Item List.
3. Next, check the Include Inactive box located at the bottom right part of the page.
4. Then, select the Item drop-down menu, and click Re-sort List. 
5. Choose OK.
6. Once done, close and reopen your company file.

After that, go ahead and create a recurring invoice for the Managed Services items again. Check to see if you still experiencing the same issue. If yes, we can proceed to another set of solutions. 

If the issue persists, you'll now have to utilize the Verify and Rebuild data tool. This method will determine if there are any issues within your company data and self resolves them. Let me guide you on how:

Verify data

1. Start with closing all the open pages in your QBDT program by going to the Window tab.
2. Next, choose Close All.
3. Once done, navigate to the File menu.
4. From there, select Utilities and click Verify Data.

Rebuild data

1. Go back to the File tab and select Utilities.
2. Next, choose Rebuild Data.
3. Select OK once you receive a message to back up your company file.
4. The process will begin as soon as the backup is done.
5. Then, when you see the message "Rebuild has completed" click OK.
