Unable to see Quality collection plan in LOV of Grant privileges form

Hi

I am trying to create a collection plan using API. I called create_ collection_plan api then add_element api and then complete_plan_processing API. After this, when I try to see my plan in front end I am unable to see, in backend I can see the plan. I tried providing grants using Grant Privilege form but unable to see the plan in the LOV. Where as when I try to create another plan front end , I can see the plan in the LOV of Grant privileges form. One strange thing, I can see those plans(created using API) in the LOV after few hours. Please let me know if there is any background process that has to run explicitly.
