OpenStudio 1.14 Not able to edit loaded custom schedules

edit

Why when I am in the Schedule primary tab, and in the Schedule Sets Folder, I can create a custom schedule set by dragging over custom schedules that I have loaded into the library to create custom default schedules, but when I click on the Schedule folders, my custom schedules disappear even I reload them into the library? What schedules do show are the default schedules under schedule rulesets in the Library folder and nothing under the My Model Folder. With this, I am unable to display or edit my custom schedules. Thank you for your response.
