Select User does not work

Hi,

Everytime I add a new member I have to use the “reset” button besides the “Select top level” field.
Then I have to rearrange all the members in the desired order again.

There is for the moment no other way to add the new member tot the chart.

This is because the “Select User” field isn’t showing the new member after I added a new member. Also using the “add” button makes no difference.

Is this a bug? Is it something in the settings? Can I fix it myself?

Thank you for looking in to it.
