scroll does not work when max-height is 100%

I'm facing an issue where when my max-height is set to 500px, the scroll appears. However, if i set the height to 100%, the scroll will never appear for one of my tables. Strange enough, my other table works fine.

scss code:

.card-box {
  box-shadow: 0 4px 24px 0 rgb(34 41 47 / 10%);
  margin-bottom: 8px;
  background-color: #fff;
  background-clip: border-box;
  border: 0 solid rgba(0, 0, 0, 0.125);
  border-radius: 0.5rem;
  padding: 10px;
  max-height: 100%;
  overflow: scroll;

  .ant-tabs-tab {
    font-weight: bold;
  }

  .ant-table-tbody {
    color: #222;
  }

  .h6-title {
    color: blue !important;
    font-weight: bold !important;
    font-size: 32px !important;
    margin-left: 5px !important;
  }
}

If i set to 500px:

If i set to 100%:
