Fortnite Save the World Storm Shield (PS4)?

I've last made the storm shield Defense 8 and because I could only place 7, 8 buildings when I wanted to do the debt defense 9, I could only place 1-2 buildings what I think I could stupid someone say how can I place more?

Storm Shield: Twine Peaks

Momentary flash level from me: ⚡123

I thank you in advance

There's a certain limit to what you can build in a storm shield should also be displayed normally (Remaining to build) or so. Since you are in Twin Peaks already at the 9th SSV, I think that you've built enough that the limit is reached. Try a wall or dismantling and then look if you can build something again. If yes replacet you stop if no you have to deal with it

Hope it makes it a little clearer
