'I can't see the burning effect in my MCPE'

What I expected to happen was...:
I just guessed that MCPE will show the burning effects whenever these were considered to happen.

What actually happened was...:
If I enter the lava or make fire on me, I can't watch burning effect at anywhere! Something happens wrong I think!

Steps to Reproduce:
1. Just put yourself into the Lava or make fire on you.

PS: I'm IOS iPad1 user so some other player will not suffer from this problem.
