I'm trying to port a capability from 1.12 to 1.15 and keep getting this error, but I don't understand where I'm registering it twice.

Here are the capability classes:

Spoiler

public interface IStand
{
    void setStandID(final int p0);

    void setStandAct(final int p0);

    void setStandOn(final boolean p0);

    void setJojoPower(final int p0);

    void setPowerSpawned(final boolean p0);

    void setPlayerStandName(final String p0);

    int getStandID();

    int getStandAct();

    boolean getStandOn();

    int getJojoPower();

    boolean getPowerSpawned();

    String getPlayerStandName();

    void setStandRemoved();

    void cloneSaveFunction(final IStand p0);
}

public class IStandStorage implements IStorage<IStand>
{
	public INBT writeNBT(Capability<IStand> capability, IStand instance, Direction side)
	{
        CompoundNBT props = new CompoundNBT();
        props.putInt("standID", instance.getStandID());
        props.putInt("StandAct", instance.getStandAct());
        props.putBoolean("StandOn", instance.getStandOn());
        props.putBoolean("PowerOn", instance.getPowerSpawned());
        props.putInt("PowerID", instance.getJojoPower());
        return (INBT)props;
      }
      
      public void readNBT(Capability<IStand> capability, IStand instance, Direction side, INBT nbt)
      {
        CompoundNBT propertyData = (CompoundNBT)nbt;
        instance.setStandID(propertyData.getInt("standID"));
        instance.setStandAct(propertyData.getInt("StandAct"));
        instance.setStandOn(propertyData.getBoolean("StandOn"));
        instance.setPowerSpawned(propertyData.getBoolean("PowerOn"));
        instance.setJojoPower(propertyData.getInt("PowerID"));
      }

Registering the capability:

public static void registerCapabilities()
    {
    	CapabilityManager.INSTANCE.register(IStand.class, new IStandStorage(), IStandCapability::new);
        MinecraftForge.EVENT_BUS.register(new CapabilityHandler());
    }

Show more of your code. Preferably as a git repo.

Heres the repo:

Switched it to ClientSetupEvent.

https://github.com/Novarch129/Jojomod-1.15.2

Theres a lot of commented out code due to this being a port of a 1.12.2 mod.
