Hello Javat,

Can you please provided the cell zone conditions . The zones are not in contact with each other that is the reason you are experiencing the connectivity issue. You can use the merge option in the cell zones of these two regions and  make it is as a connected single entity . I hope this helps you.

Please follow this user guide link on how to merge cell zones .

Thanks,
