Failed to include Levels into IOS package

I’m trying to package my IOS app and when I ran it on my phone, I found that the level cannot be opened, I have already add all the maps I needed into [Project Setting → Packaging → List of maps to include in a packaged build], here are my settings.


Please ignore the spelling mistake.
I check the path several times and I am sure these settings are correct.
The 821_Leve seems not be included into the package.
Is this a bug or I make some mistakes?
I want to know the reason and a solution to fix the problem.
Thank you!
