Solved: Explosion doesn't remove any blocks

So I want to make that right clicking a block under specific conditions will make the block instantly explode. The explosion particle is present, it bounces and damages entities, but no blocks are detroyed. And there's this weird thing when I right click the block on the -Z and -X axis the explosion deals 1 hp damage to entites besides the player, but on the +X and +Z it kills every entity instantly. Any way to fix this behavior or make the right click block action work server-wise too?

Edit 1: forgot to mention that I did use the Do In the server-side world, still doesn't help.

Edit 2: I realized that the block should not be there so the explosion works...
