Difference transform in ROS tf and Isaac stage


I am using “ROS1 subscribe joint state” and “Articulation controller” to drive a built-in UR5e model from a ROS topic. On the publishing side, we are using the default calibration file with no changes.

The problem we are having is the transform values are not the same in "rosrun tf " and in Isaac editor which is causing us problems in our simulation.

Here is a comparison of the two:

because of these differences, it is not able to pick the intended target as we have in the real scenario.
Are there any physics settings that we are missing or some other thing, we are not sure what is the root cause?
