Can’t Unset Pre-Order Date

I had some products I was releasing for preorder approximately a month out. My partner and I determined we were in a good enough spot to fulfill the orders to we edited all of the pre-order products and unchecked the Pre-order status. After saving the product, the products in the cart would still show “This product will be available to ship in X days”. We went back into editing the product and this time we removed the pre-order date as well. We received the same message. I reloaded the product in the admin area and the pre-order dates did not save (if I removed them and hit save/update, the dates would fill back in with whatever was selected). We tried setting the date to today’s date but the issue still happened where the dates reverted to being a few weeks out. We ended up disabling the plugin all together but it appears to have canceled all orders that were preordered.
