disabledDayNames + sundayStart disables days one column to the right of expected

Easy replicable with the codesandbox demo - just add sunday-start and you will see that instead of Su + We calendar disables Mo and Th.

        <h4>Disabled Day Names</h4>
        <h5>...</h5>
        <functional-calendar
          class="calendar"
          :is-date-picker="true"
          :disabledDayNames="['Su', 'We']"
          sunday-start
        ></functional-calendar>
