Orphan element from corridor during template modification.

Hello to all

I was using Open roads 2019 release smoothly .After getting notification for 2019 release 2 updated the software after which the software started some problems due to which i had a fresh install and updated it again to the current version 10.07.01.32. It has again started to giving problem as every time i try to modify or change a template on a corridor, the template leaves orphan element such as base layer, curbs. which cannot be deleted even if the whole corridor is deleted . if somebody could help what is the reason and why the element cannot be deleted.
