Can't refill?

[FreckledPig147]

During play (on the overworld map or pre-battle menu, if you tap on the + sign next to the ship energy, the refill menu pops up, but the left refill option is always blackened, even with ship energy remaining and normal energy. If I compared it to the option on the right, it would probably mean I refill 1 energy with 1 ship energy. Am I mistaken as how that refill option works? Below is a screenshot of the black refill button. I still have 1 ship energy remaining in the picture.

Wonder the same think. But watching videos from arcadego’s channel made me realize that you earn it somehow.

You just click on the gem. 1 gem = 3 ships. No idea what the other option is.

You get them from daily challenges.

You will get three once you have finished daily objective (you may get 1000 coins sometimes).

You have to have those in your inventory to use them. I wondered same & once I accepted one from gift box from daily challenges, I wondered why I only got 1 ship energy instead of 3, but the other 2 are there & show up if you need a refill later.
