PosePublisher Plugin unexpected behaviour

Good afternoon to everyone. I have the following problem:
I’m running a simulation with one turtlebot that is able to move simple objects in a rectangular arena. Both the arena and the objects are defined in sdf format.
This is the code for the objects:

<?xml version="1.0" ?>
 <sdf version="1.9">

	<model name ="object">
		
		
		<link name="link_object">

			<visual name="visual_object">					
				<geometry>
					<cylinder>
						<radius>.1</radius>
						<length>0.08</length>
					</cylinder>
				</geometry>
				<material>
					<diffuse>1 1 0 1</diffuse>
				</material>
			</visual>

			<collision name="collision_object">
				<geometry>
					<cylinder>
						<radius>.1</radius>
						<length>0.08</length>
					</cylinder>
				</geometry>

				<surface>
					<friction>
						<ode>
							<mu>0.05</mu>
						</ode>
					</friction>
				</surface>

			</collision>

		</link>
	</model>
	

</sdf>`

And this is the code to build the arena:

<?xml version="1.0" ?>
<sdf version="1.9">
	<world name="arena">

	<scene>
		<ambient>1 1 1 1</ambient>
		<grid>0</grid>
	</scene>


	<physics type="ode">
		<max_step_size>0.003</max_step_size>
		<real_time_factor>1.0</real_time_factor>
	</physics>

	</model>


</world>

The problem that I’m facing is that when I try to push an object with the turtlbot the pose on the corresponding topic is updated with the right value only for the objects 2,3,4. If I move the object 1 the values of all the other objects are being updated, except the pose for the object 1.
I think there must be a problem on the PosePublisher plugin but I don’t understand what I’m doing wrong.

Thanks in advance for your help.
