Carlotta's swimsuit skin weight error?

[JoI9384]

I am working on a mod using the merged skeleton for Carlotta’s swimsuit skin, but I encountered an error.
After applying the weights from Component 1 to the mesh located in Component 3, I noticed that the movements were not synchronized. Upon closer inspection, I found that Component 1 and Component 3 shared the same weight numbers, but those same weight numbers behaved differently in each component.
When I moved the mesh from Component 3 to Component 1 and tested it, it followed the movements of Component 1 correctly.
Since this behavior is different from what I understood about the merged skeleton, I would like to ask whether this issue can be fixed or if it is an unavoidable limitation.
Please understand if the wording sounds a bit awkward, as I am translating this with ChatGPT.

Export original model as mod without any edits. If it'll work as intended, it means you've made some weighting errors.

Since the mesh’s movement depends on being in a specific component and position, exporting the original file as-is does not cause any issues.

It may be easier to understand if you look at this image:

Currently, the parts that move abnormally are located in Component 3.

However, if I move these abnormally moving meshes to Component 1 without making any weight adjustments, they appear normal, as shown in this image:

(You can confirm that the component has changed by checking the texture state.)

In the case of the original merged skeleton, using the weights from a specific component would result in the same movement across other components as well.
But in this case, since the same weight numbers exist in two different components and behave differently depending on which component they are assigned to, it feels more like a per-component behavior.
