Minecraft PS4 not letting me place blocks in certain areas

I have recently made a Minecraft creative world. On the PS4 Minecraft console edition and it is my favorite world. Meaning I build on it constantly and always reaching the animal spawn limit and stuff like that. At the beginning I made a piston powered color changing Beacon. I bet you have seen a few of those before. Recently I was looking at it and saw it wasn't changing as many colors as before. I go in to wear all of the glass gets pushed by the Pistons and see Pistons are broken and glass not there. Like any normal person I think someone griefed my beacon so I go to fix it. But in the spots where it was missing I was not allowed to place blocks. I could place blocks everywhere else but not those certain spots. I'm then a very confused and almost rage because it is one of the first things I ever built and it was so cool. I have looked up trying to find answers but nothing came to my arrival. Most things were talking about how they were not allowed to place blocks in large chunks of area. But I was only not allowed to place blocks in certain blocks. I was also trying to make another one on top of it but was not allowed to place a lever in three spots and only one. I even tried exiting the game and going back in but nothing changed. All of this stuff is quite new to me because I have never had this happen in any of my other Minecraft worlds. Is it possibly due to the amount of items in my world. Or just a simple bug that will annoy me forever. Answer would be very nice thank you.
