let's determine I have a bullet that hits a block and when it hits a block it puts AIR blocks within a radius of 25 blocks and then it does it 2 TIMES (because it should do it once)
and last time invisible blocks are created in places ah where there was no AIR.

This sounds like a client/server desynchronization issue.

It can be solved by putting the entire procedure in an if statement with the condition (not(is provided world client-side)) that will force it to run on server-side only (which includes the singleplayer internal server) and will prevent it from placing invisible/ghost blocks.

Show the procedure and explain how you trigger it please

This may also help to determine on what side your procedure runs: https://mcreator.net/wiki/how-use-debugger

here is the java code:

package net.mcreator.quantumdestruction.procedures;



import net.minecraft.world.level.block.Blocks;

import net.minecraft.world.level.LevelAccessor;

import net.minecraft.world.level.Level;
import net.minecraft.core.BlockPos;
import net.minecraft.world.entity.ai.goal.RemoveBlockGoal;


import org.apache.commons.io.input.BOMInputStream;

public class BoomProcedure {



    public static void removeBomb(LevelAccessor world, double x, double y, double z){
        world.setBlock(BlockPos.containing(x, y, z), Blocks.AIR.defaultBlockState(), 3);
        if (world instanceof Level _level){
            _level.updateNeighborsAt(BlockPos.containing(x, y, z), _level.getBlockState(BlockPos.containing(x, y, z)).getBlock());
        }
    }
    public static void execute(LevelAccessor world, double x, double y, double z) {

//        world.setBlock(BlockPos.containing(x, y+7, z), Blocks.AIR.defaultBlockState(), 3);

        int RAY = 25;
        for (int index0 = 0; index0 < (int) RAY; index0++) {
            for (int index1 = 0; index1 < (int) RAY; index1++) {
                for (int index2 = 0; index2 < (int) RAY; index2++) {
                       if ((index0*index0+index1*index1+index2*index2)<RAY*RAY){
                        removeBomb(world,x-index0, y-index1, z-index2);
                        removeBomb(world,x+index0, y-index1, z-index2);
                        removeBomb(world,x-index0, y+index1, z-index2);
                        removeBomb(world,x+index0, y+index1, z-index2);
                        removeBomb(world,x-index0, y-index1, z+index2);
                        removeBomb(world,x+index0, y-index1, z+index2);
                        removeBomb(world,x-index0, y+index1, z+index2);
                        removeBomb(world,x+index0, y+index1, z+index2);
                     }
                }
            }
        }
    }

world.setBlock(BlockPos.containing(x, y, z), Blocks.AIR.defaultBlockState(), 3);
if (world instanceof Level _level){
_level.updateNeighborsAt(BlockPos.containing(x, y, z), _level.getBlockState(BlockPos.containing(x, y, z)).getBlock());
}

This code looks a bit suspicious to me, and also does not look like it is MCreator generated
