Sort order in folder pane

Why do ProjectWise sort folders differently in the Folder and the File Pane (left and right view pane). (see parent folder 12 Gældende grundlag in image below)

In the folder pane A comes before 0 (wrong sort order) but in the file pane 0 come before A (witch is correct according to the ASCII value).

Can I influence the sort order in the folder pane, because it is sorting wrong?

Anyone ?
