1 - According to your initial Query, your problem has now been resolved since you can now see your Benefit Plans in pa30. For the benefit of all users, please mention how you were able to solve your initial query and then close this thread.
2 - You should create a new query whose subject would be "Benefit Plans not showing in Fiori App", and mention how you configured your app, so that someone familiar with that part of the configuration could notice your thread an help you.
