Hi smoothrider
The point one could be because there is no enough stock, we will need to look to the settings, and as well for the point 2.
Please, I have to ask you to open a private ticket in order to provide us with your website credentials to take a look.
This is the link to the private ticket: https://stockmanagementlabs.ticksy.com/
And remember to make a reference to this post.
Best Regards,
Andrea.
