[OptaShift Employee Rostering] It is not possible to set employee availability

In Employee roster, it is not possible to set an employee availability in the Edit availability modal window, as the Apply button does not work. It is only possible to set the availability to UNAVAILABLE, as it is the default option after clicking on canvas.

Moreover, the list of availabilities in the modal window repeats the values (UNAVAILABLE, UNDESIRED, DESIRED) multiple times. See screenshot.
