I'm using Magento 126.96.36.199.
There are three recent orders that do not appear in the Sales > Orders panel. Here is a screenshot of the most recent orders, please see the order numbers:
However, the 3 missing orders are present in the database:
The strange thing to me is that the orders also appear in the "last 5 orders" widget on the dashboard, and I can open them by clicking on them there. So Magento seems to be loading the data correctly, just not loading it into the orders grid.
Any help or suggestions is much appreciated.
