I cannot go to next level. It says visit storage and redecorate which I have done?

We already have an answer for a similar question which you can see here:
I can’t understand why it says I have to redecorate to move to the next..

If you have more answers to add you can do that below.

To reach the next level, you must add the required number of Flower indicated next to the flower icon in the upper right. Game is indicating you have the number in storage, just need to place them on the island to count.
