MIKMIDIClientSourceEndpoint and MIKMIDIClientDestinationEndpoint virtual endpoints appear in the list of virtual endpoints with their roles reversed

When I create both a virtual endpoint using MIKMIDIClientSourceEndpoint (which as documented creates an endpoint that lets you send MIDI out of your app) and a virtual endpoint using MIKMIDIClientDestinationEndpoint (which is used to receive MIDI data into the app) it seems they get automatically grouped together but in reversed roles.

This is how I declare the virtual endpoints:

virtualInput = MIKMIDIClientDestinationEndpoint(name: "Virtual Input", receivedMessagesHandler: listenVirtualBlock)
 let error:NSErrorPointer = NSErrorPointer(nilLiteral: ())
 virtualOutput = MIKMIDIClientSourceEndpoint(name: "Virtual Output", error: error)

First I see a call to connectionManager(_:shouldConnectToNewlyAddedDevice:) with the following device:

<MIKMIDIDevice: 0x280891b40> Virtual:
        Entities: {
            <MIKMIDIEntity: 0x280891ac0> Virtual Output:
        Sources: {
            <MIKMIDISourceEndpoint: 0x281359290> Virtual Output,
        }
        Destinations: {
            <MIKMIDIDestinationEndpoint: 0x281359560> Virtual Input,
        },
        }

And then when I go through the list of virtual endpoints from MIKMIDIDeviceManager.shared.virtualSources / MIKMIDIDeviceManager.shared.virtualDestinations, they appear also in reversed roles.

[<MIKMIDISourceEndpoint: 0x281348c60> Network Session 1, <MIKMIDISourceEndpoint: 0x2813b5860> Virtual Output]

[<MIKMIDIDestinationEndpoint: 0x2813b5980> Network Session 1, <MIKMIDIDestinationEndpoint: 0x28136ce40> Virtual Input]
