❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

When a Slimefun block with Falling Physics is placed and then updated, the Vanilla version of the block gets duplicated. This behavior also occurs when a block update is triggered. This bug was observed on a server running Minecraft Paper version 1.20.2 and the latest version of Slimefun.
I demonstrated it here with Galactifun, but it happens with all addons that use blocks with physics.

📑 Reproduction Steps

1. Place a Slimefun block with Falling Physics (e.g., Gravel with SLimefun Tag) on the ground.
2. Observe how the Vanilla version of the block gets duplicated.
   (Optional)
3. Trigger an update on the block.
4. Observe how the Vanilla version of the block gets duplicated.

💡 Expected Behavior

When a Slimefun block with Falling Physics is placed and updated, only the Slimefun block shouldn't be affected, without duplicating the Vanilla version.
