running the root gazebo model device and a link device fails to merge

[elael]

I have a SDF model with a link. If I start the device tied to the root model, and then try to run the device for a link, I get

device squidbot is assigned to two tasks that cannot be merged,
OroGen.rock_gazebo.ModelTask{7}:0x555929e214e0,
  no owners,
  arguments: ,
    conf: ["default"],,
    model_dev: MasterDeviceInstance(squidbot[CommonModels::Devices::Gazebo::RootModel]_dev),,
    underwater_camera_dev: MasterDeviceInstance(underwater_camera[CommonModels::Devices::Gazebo::Link]_dev),,
    job_id: 5,
OroGen.rock_gazebo.ModelTask:0x555929fdc6b8,
  no owners,
  arguments: ,
    conf: ["default"],,
    model_dev: MasterDeviceInstance(squidbot[CommonModels::Devices::Gazebo::RootModel]_dev),,
    job_id: 1

I checked and it seems that the model device is indeed the same, which leads me to believe that the problem is with the job ID
