Can't place or remove blocks in parts of my server or they break and can't be edited again

I have no idea how this happens but does anyone know how prevent it or fix it

Use /repair to remove the blocks.

As Wumbo said, but not just the block, it will fix the space so that blocks can be placed without breaking.

Unless it’s a natural block

god… this reminds me of the old woven flax mats besides the fact embers don’t work
