Hello again, PIAlgw. Thanks for keeping us updated. 

As mentioned by my colleague @AlexV, when creating an invoice, the Accounts Receivable (A/R) use is the default account. In your case, it could be that the default A/R was rename to Other Receivable.

To isolate the issue, let's use the Audit log tool to help trace the changes made. Here's how:

1. Click the Gear icon at the top.
2. Select Audit log.
3. Click the Filter dropdown menu.
4. Select All Users, All dates, and Show all events.
5. Click Apply.

From there, see if there are some changes made to Accounts Receivable. 

Here's a detailed article about this audit report: Use the audit log in QuickBooks Online.

Let me know if there's anything else you want to ask. I'll be right here if you need anything else. Have a good one!
