robot_localization from map to odom does not move on Ubuntu-18.04 Melodic

edit

I am using robot_localizationin my project. I'm fusing data from camera odometry, imu, depth sensor and usbl (XY position sensor) as odom0, , odom1, odom2 and imu0 respectively. I followed the instructions in configuring the parameters on official documentation and set the frames as a "fixed frame" and a "moving frame". In my case the moving frame is the odom frame and the fixed frame is the base_link.

The documentation tells me this should make the ekf_localization node publish the transform from map to odom if the publish_tf param is set to true. The launch file both for the "fixed frame" and the "moving frame" is below together with the tf tree:
