How to receive all data (array) from dynamic input in react.js?

Question

I am trying to receive data from a dynamic input (article), but it returns only an array with the two first element, I do not understand why, because I receive data from another dynamic input (chapitre) with no problems?

{
  chapitreList.map(
    (partItem, index) => {
      return (
        <div key={index}>
          <label for="namec">  chapitre {index+1} :</label> 
          <input type="text" name='namec' id='namec' className ="form-control" value={partItem.chapitreName} />
          <input  type="number"
                  name='soldc'
                  id='soldc'
                  className ="form-control"
                  placeholder={partItem.chapitreDepense}
                  onChange={(e) =>
                    setchapitresolde((prev) => {
                        prev[index] = e.target.value;
                        return [...prev];
                      }
                    )
                  }
          />

          {
            partItem.articleList.map(
              (artItem, inde) => {
                return (
                  <div key={inde}>
                    <label for="namec">  article {inde+1} :</label>
                    <input type="text" name='namea' id='namea' className ="form-control" value={artItem.articleName} />
                    <input  type="number"
                            name='solda'

                            placeholder={artItem.articleDepense}
                            onChange={(e) =>
                              setarticlesolde((pre) => {
                                pre[inde] = e.target.value;
                                return [...pre];
                              })
                            }
                    />
