Default Remesh using ICEM replay - CFX throwing error with symmetry plane

selvavm is on a distinguished road
My geometry is a simple box inside a domain as shown in Figure. I want the box to move towards the right (1 degree of freedom). I have set the remesh settings as per the guide and I am doing ICEM replay method.

When I run the simulation, after few iter, the interrupt control reaches, then the remesh starts and meshes. Then CFX solver shows error in symmetry plane as shown below.

ERROR #002100013 has occurred in subroutine Chk_Splane.
The symmetry boundary condition requires that the boundary patch
mesh faces form a plane or axis. However, face set 8 in the
symmetry boundary patch

is not in a strict plane, which means that at least one of its
faces is not parallel to the others. To make the solver run
you can do one of the following:

(1) Make sure that this symmetry boundary patch is in a plane or
axis by checking and regenerating the mesh.
(2) If the symmetry boundary patch is an axis rather than a
plane, change the tolerance of the degeneracy check by
increasing the value of the Solver Expert Parameter
'degeneracy check tolerance' (the default value is 1.e-4).
(3) Increase the value of the Solver Expert Parameter
'vector parallel tolerance' (the default value is 1 deg.).
Note that the accuracy of the symmetry condition may decrease
as the tolerance is increased. This is because the tolerance
is the number of degrees that a mesh face normal is allowed
to deviate from the average normal for the entire face set.
Infact, I imported the reference geo into ICEM and loaded the replay script. This works flawlessly.

Can anyone help me?
