Innovus - Poly alignment issue

After the placement stage in the innovus, I could see the polys of the placed standard cells misaligned. Please see the screenshot below. This is causing many DRC violations when the GDS is imported in virtuoso . What could be causing this issue and how can we solve this? Any help is greatly appreciated.

Thanks in advance

regards

Hi Shreyas,
you can check if the cells are legally placed in Innovus with check_place/checkPlace.
You can also check if the standard cell descriptions in the LEF and the GDS have the same contents and origin.
