Quickbooks Desktop Changing Product Numbers

We use QB Desktop Enterprise 2019, and recently (started in February) we have been encountering issues with our inventory numbers.

It took us a while to notice, so the error wasn't caught until May, and we have started keeping a physical record and checking it often. 

What is happening:

QB is changing our assigned inventory names.
We had a 11040 and a C11040 - at some time between February and May/when we caught, the item named 11040 changed its name to something unrelated.

Between yesterday (15th) and today (16th), we had an item named 71104 change entirely on it's own to 91104 - this caused two entries of the same name but with different ListID's, which is the reason we caught it as we export the ListID's for external reports.
Yesterday they were normal. There are only 2 people in the building that access and make changes to inventory, one is myself and the other is our CPA, we work in the same room and never make inventory changes without it being discussed.

A similar issue happened at the beginning of July, on or before the 5th, which prompted us to print our entire O/H report to cross reference.

This has never happened or been an issue prior to February and we can't pinpoint the day it started.

Has anyone else experienced this and if so, how can we correct it?
Our database is backed-up every night and updates are always done immediately.

People come to QuickBooks Learn & Support for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

  1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
  2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
  3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
  4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
  5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
