Cannot insert or see models even though gazebo_model_path is set

I am having issues inserting custom models into gazebo. Here is my file structure: - lawnbot_ws - src - lawnbot_desription - models - grassplane - meshes - model.sdf and model.config - package.xml Gazebo shows: /home/josiah/PycharmProjects/lawnbot_ws/src/lawnbot_description/models in the insert tab, however it does not show a drop down for actually inserting the grassplane model! I also have the following line inserted in the package.xml file of the lawnbot_description package: I do not understand what is wrong. I am calling: roslaunch gazebo_ros empty_world.launch extra_gazebo_args:="--verbose" in the terminal and the gazebo_model_path shows: /home/josiah/PycharmProjects/lawnbot_ws/src/lawnbot_description/models
