I originally posted this on the Magento Forums, hoping someone knew how to resolve this. My original request for help on the Magento Forums, which includes some screenshots, is here:

I eventually came to an erroneous conclusion that this was being caused by an extenstion I bought from Amasty called "Custom Stock Status". After working with Amasty customer support, they were able to recreate the issue without having their extension installed at all. I then tried on my test server with a fresh install of Magento 2.3.2, and also was able to re-create the issue. So this issue has been replicated by an independent source.

Also, if you have MAP enabled and set the MSRP to the same price as the item, the system still thinks there is a price difference and tells you to add to the cart to see the price.

All of these issues go away if you set the "Display Out of Stock Products" option to "No"...

_ OR _

Keep "Display Out of Stock Products" to "Yes" but Assign the "Default Source", in addition to the other sources, to any one of the Configurable Product items and set the quantity > 0. The "Display Out of Stock Products" option in conjunction with Multi-Source Inventory (MSI) seems to be the trigger for this issue.

Some screenshots attached...
