Minecraft Griefergames can't place anything, why?

I'm new to Minecraft and Griefergames. I would like to build some things on my property. But whenever I make a workbench and want to set it up, the next moment it disappears. Even if I go directly to "/ craft", everything I'm making at the moment disappears, at the latest after I want to place it. What can I do there?

P.s. Placing blocks etc is possible.

Use Minecraft version 1.8 to play on GrieferGames. Then you shouldn't have any more such problems.

I'm playing on the Nintendo Switch and it says "You are using the latest version of this software" but it still doesn't work.
