Have you completed your 12 checkpoints first? From what I see, you're in the level 80s range based on what's exposed.

Breakthrough unlocks at checkpoint 9, but you can only do the 1st checkpoint. If you however clear up to checkpoint 12, then the following breakthrough checkpoints will be clickable.

If you can have the screenshot of your 12 checkpoints cleared, immediately followed by the screenshot of what you just put up, with the timestamp (i.e. Date and Time), you can report it as a bug! Cause I think its weird too!
