I've used this set of modules in Odoo v9 with good results, but now when we're upgrading to v16 I get incorrect qtys in the Available and Potential fields from stock_available and stock_available_mrp.

To test the behaviour I created three products:

1. Car - Storable, manufacturing route, BoM that includes one of each:
2. Steering wheel, Storable, buy
3. Engine, Storable, buy

I set the initial quantities for the products to:
Car - qty on hand: 10
Steering wheel - qty on hand: 5
Engine - qty on hand: 3

I have stock_available and stock_available_mrp installed, and the setting "Include the production potential" set to "Quantity on hand".

Now I'd expect the product page for Car to display:
On hand: 10
Forecasted: 10
Available: 13
Potential: 3

But instead, I get "Available: 3", which makes no sense, it should be On hand + Potential. In Odoo v9 it works like this, but in v16 it seems to be broken somehow. Any ideas?
