pixi-spine bug: Resource named "..._atlas" already exists

[kule90]

I have problem last 3 days, and I am not able to solve it.

Here is simplified code:
 

  PIXI.Loader.shared
    .add("spineDataName", "spine_assets/Crab.json")
    .load(onAssetsLoaded);

  function onAssetsLoaded(loader, resources) {
    const spine = new PIXI.spine.Spine(resources.spineData.spineData);
    spine.scale.set(0.5);
    this.parentContainer.addChild(spine);
    spine.state.setAnimation(0, "animationName", true);
  }

And an error in console.log that appears is always same - in this case:
plugins.min.js:1 Uncaught Error: Resource named "spineDataName_atlas" already exists.

What I have tried:

1. version of my Pixi.js is 5.2.1, so I have tried all versions of pixi-spine up to 3.1.2;
2. clearing the PIXI loader using the reset() before loading resources;
3. using new PIXI.Loader() instead Pixi.Loader.shared;
4. making unique names for resources of Spine data,
5. making everything async function.
6. loading resources atlas separately before .json file.

Any help is welcomed.
