SystemLandscape only shows the first relationship

[asos-andrewpotts]

The SystemLandscape diagram only shows one relationship, when two software systems have more than one relationship.

Take the example below. System A has two relationships with System B:
containerA1 has a relationship with container B1
containerA2 has a relationship with container B2

yet on the diagram only A1 > B1 is shown, and A2 > B2 is missing.
I would like to see both relationships.

workspace "Data Flows" "" {
    model {
        systemA = softwareSystem "System A" "SystemA" "" {
            containerA1 = container "Container A1" "ContainerA1" 
            containerA2 = container "Container A2" "ContainerA2"
        }

        systemB = softwareSystem "System B" "SystemB" "" {
            containerB1 = container "Container B1" "ContainerB1"
            containerB2 = container "Container B2" "ContainerB2"
        }
        
        containerA1 -> containerA2 "A1 > A2"
        containerB1 -> containerB2 "B1 > B2"
        
        containerA1 -> containerB1 "A1 > B1"
        containerA2 -> containerB2 "A2 > B2"
    }

    views {
        systemlandscape "SystemLandscape" "" {
            include *
        }

        container systemA {
            include containerA1
            include containerA2
        }

        container systemB {
            include containerB1
            include containerB2 
        }
    }
}

Even explicitly including the relationship doesn't work.

workspace "Data Flows" "" {
    model {
        systemA = softwareSystem "System A" "SystemA" "" {
            containerA1 = container "Container A1" "ContainerA1" 
            containerA2 = container "Container A2" "ContainerA2"
        }

        systemB = softwareSystem "System B" "SystemB" "" {
            containerB1 = container "Container B1" "ContainerB1"
            containerB2 = container "Container B2" "ContainerB2"
        }
        
        a1a2 = containerA1 -> containerA2 "A1 > A2"
        b1b2 = containerB1 -> containerB2 "B1 > B2"
        
        a1b1 = containerA1 -> containerB1 "A1 > B1"
        a2b2 = containerA2 -> containerB2 "A2 > B2"
    }

    views {
        systemlandscape "SystemLandscape" "" {
            include systemA
            include systemB

# Explicitly include the relationship
            include a1b1
            include a2b2
        }

        container systemA {
            include containerA1
            include containerA2
        }

        container systemB {
            include containerB1
            include containerB2 
        }
    }
}

This is likely what you're seeing -> https://github.com/structurizr/dsl/tree/master/docs/cookbook/implied-relationships

Yes, that explained it fully, and got me working again. Thank you Simon for your swift response.
