MPMLink - Plant visualisation bug

In MPMLink module - When we add another resource (e.g. Skill - Assembler) to the Plant system automatically put his visual representation in random place. When I want to update its position to right location going to Plant object -> Structure -> Update Position -> setting another values, it does not move the object by these coordinates, but copies it to other location. (in tree there is no visible another object but it remains on visualisation tab). -> Windchill 13.0.2.0
