How to remove Component Outline from Bottom Soldermask

 Good day  to all,
  Please I need your  support and guide  on how to solve this Problem.I am using Orcad Pcb Editor 16.0 for my circuit design.After completing the layout,i generated the Gerber files and sent it to the company that will produce the Board but the Company sent a message to me that my Bottom Soldermask contain Component Outline.I was asked to remove  the component outline from the bottom soldermask because the presence of Component Outline in the Bottom Soldermask will expose the copper track.
  My problem now is that i do not know how to remove the component outline from the bottom soldermask.My Bottom Soldermask  Folder contains the following classes/Sub classes:
1-via class/soldermask bottom
2-pin/soldermask bottom
3Package Geometry/soldermask bottom
4-DRC Error  class/soldermask bottom
5-Board Geometry/soldermask bottom
   I would be very grateful if somebody could guide me on how to solve this Problem.Thank you for the usual Support.
   Best regards.
