Using ROS Toolbox to publish transforms between 2 frames on topic /tf_static but RVIZ doesn't recognize them.

Hello there!

I'm using ROS Toolbox to publish the transform between two frames. This involves using the tf2_msgs/TFMessage message on the /tf_static topic, with the frame_id set to 'Mutter' and the child_frame_id set to 'Tchter', as shown in the picture:

Simulink publishes the transforms just fine and it's visible on my Virtual Machine

The problem is neither RVIZ nor tf_ros package recognize these frames, as shown below.
