I'm making a list, I have categories, each category has its intervention and you have to check it based on what corresponds to the problem.

CheckList.vue

<table class="table table-bordered">
          <thead>
            <tr>
              <th rowspan="2" style="vertical-align: top">Categoria</th>
              <th colspan="2">Existe</th>
              <th colspan="3">Estado</th>
              <th colspan="2" rowspan="2" style="vertical-align: top">
                Observación
              </th>
            </tr>
            <tr>
              <th>Si</th>
              <th>No</th>
              <th>Bueno</th>
              <th>Regular</th>
              <th>Malo</th>

          >
            <tr>
              <td colspan="8" class="table-secondary">

There is no problem when selecting the first radio option. The problem is that when selecting the second radio option in the second row, intervention 2, the first one is deselected.
