Cannot access the next Island in Mark of the Ninja

I can’t advance  in Mark Of the Ninja the next battle is unlocked but the icon to access it won’t activate here’s a screen shot…note how the completion bar atop the island is empty but the swords to activate the Island in the bottom right hand corner is still gray as if though it is still locked or already completed? can you please fix this because I have gone from 3rd place all the way down to 7th and its infuriating to lose because of a glitch. I’m just lucky I didn’t spend any gems to unlock this battle but I have spent gems to unlock a few before it and now its all for nothing if this doesn’t get fixed before the challenge ends.

 

 

You only have 30 battles in total (!) for the 30 islands. The more important screenshot is the one before, where it says e.g. 27/30.
Which means 27 battles (!) of 30 possible, not 27 islands done of 30 …

So if you ever attacked 1 island twice or got a crash (other than 0%) and had to replay: you can’t reach the end any more …
