Good food did not work in adventure Tombs of Terror

I played hero Reno in Tombs of Terror, the initial health of my hero is 15.
I have Sr. Tomb Diver in my deck, and I find a Hearthstone which has the effect:
Start of Game: Draw this. Escape to the Tavern and remove this from your Adventure deck.

When I battle with the first boss, I triggered the Hearthstone. I escape to the tavern. Then I find a Good food which has the effect:
Increase your starting Health by 5.

After I got out the tavern, and the health of Reno is 20. However when I try to battle with another boss(1/8 the first boss), when the game starts, the health of my hero is 15.
The good food did not wok.

I also encounter the same problem for second boss(2/8), when I buff the hero health to 30, and when the game starts, the health was cut to 25.

The bug is really annoying, I am trying to buff the health of my hero to 300. Did you restrict the heal of hero at each boss, from the first to the eighth?

Any update? I am waiting for your response?
