Ladder Editor CE _ Yaskawa Dx200 Problems

I am currently trying to edit some rungs of logic in the Ladder Editor CE application on my Yaskawa Programming Pendant. I can edit certain rungs of logic , but on other rungs it tells me that i dont have the correct user level. I am currently unaware of how to change my user level. I have the PP security level set to Maintenance or Safety. I believe safety is the highest level security clearance that you can get on the pendant so im not sure what im overlooking or doing wrong. Any thoughts?? Also i do not have the manual to this application so if anyone knows how i might could get some information on that it would also be greatly appreciated.

Thank you all for your help!
