@Mohamad_Abujarad latest CubeOrange+ has 3 ICM45686 IMUs. One of the two IMUs sits below the mass on IMU board. Remaining two IMUs with marking I4586 are visible in you image. So all is well.
But now that you have opened the Cube,the integrity of the hardware is gone, please do not reassemble and use this module in flight critical operation.
