SLAM Toolbox : "Warning: TF_REPEATED_DATA" when running rosbag in ROS Noetic. How do I get rid of this warning ?

edit

My goal is to use the SLAM toolbox on ROS Noetic with a rosbag (recorded on ROS Melodic). When I launch the SLAM toolbox in one terminal and play the rosbag in another terminal and open RVIZ in a third terminal. I get the following warning message on the terminal that launches the slam toolbox:

Warning: TF_REPEATED_DATA ignoring data with redundant timestamp for frame odom at time 1609136889.260522 according to authority unknown_publisher at line 278 in /tmp/binarydeb/ros-noetic-tf2-0.7.5/src/buffer_core.cpp

I also get the following warning on the terminal that launches RVIZ :

[ WARN] [1609407684.995474563, 1609136889.060521646]: TF_REPEATED_DATA ignoring data with redundant timestamp for frame odom at time 1609136889.260522 according to authority unknown_publisher

My rosbag has the following topics published :

1. /scan

2. /odom

3. /tf

Why do i get this warning and how can I get rid of it ?
