My mod confuses Stone with Cobblestone?

Hello!

I have a problem with procedures. So I just started using Mcreator today and have this issue with the program seemingly confusing Stone with Cobblestone.

The first one works great:

Player right clicks block:

If Item in main-hand is “StoneChisel” AND is Get block the same block as “Stone”

   (

   if not in game mode CREATIVE

      (

      Deal “1” damage to item in main-hand;

      );

   Swing main hand;

   Play break effect of “Stone”;

   Replace block with “Cobblestone”, keep state;

   Spawn item/gem “Pebble” <…>;

   );


This just simply replaces stone with cobblestone when right-clicked with stone chisel and drops pebble right above it, no problems here.
The problem starts, presumably, in the next procedure, it’s a bit more complex (I hope my pseudo code-like formatting helps):

Player right clicks block:

If Item in main-hand is “Stone Chisel” AND Is Get block the same block as “Cobblestone”

   (

   If Random Int 1…10 = 1

      (

      Swing main hand;

      Remove block and spawn break particles;

      Play break effect of “Cobblestone”;

      Spawn item/gem “Stone Axe Head”;

      If not in game mode CREATIVE

         (

         Remove “1” “Stone Chisel” from main inventory

         );

      );
else

   Swing main hand;

   Spawn “10” particles <…> type ASH;

   If not in game mode CREATIVE

      (
      Deal “10” damage to Item in main-hand;

      );

   );

Yes, I did nest three if statement and yes, I did use RNG to determine loot, I just don’t want to mess around with variables and loottables for now.

The exact problem is: while playtesting right clicking STONE removes chisel as if it was a COBBLESTONE that was clicked, so it executes the second procedure for some reason while at the same time executing the first one too (because pebble also spawns).

I have a suspicion that the mod executes both prosedures consequently, spawning pebble, turning stone into cobblestone and realising that (somehow) it was cobblestone that was clicked all along! But that’s just a theory and I don’t really know how to test it nor fix it.

So overall,
I don’t get it :(

Can anyone explain?
