A screenshot isn't needed.

The level amount on your den page is your fully completed level amount, it doesn't count partly completed levels. As you haven't fully completed level 10 in both terrains, you haven't finished a total of 20 levels yet, making it 19 levels completed

If the highest level shows as 10 on the explore page, that means you have reached level ten, but you're still on level ten and haven't completed it.

If both the swamp and the forest say you're on level 11, that means you have fully completed level 10 in both, and it should say you've completed an overall of 20 entire levels.

If that's the case, please post a screenshot.

Otherwise you need to fully complete level 10 in both places, leveling up to where it says you've reached level 11 in both the forest and the swamp.

So no I'm not on 11 but it says 19 I don't think 9+9=19 that's why I think it's a bug

You need to complete level 10 swamp to progress to level 1 jungle.
