As per the system design active status precedes all other status.
For example if you select All Products as active, the system by default considers All Products as active status.
Despite this if one of the product is blocked it acts as a contradiction hence it system considers the product as active.
Explicitly mention the products which have to be Active and Blocked( for the transport lane to stop it from being proposed in the source of supply list in Sales Order).
Also you can make use of product category option in transport lane.
