sorting order terminals

is it possible that in the current 0.1 dev is an bug together with the plugin?
Sorting the terminals in the pugin works. After that I closed QET without saving. Importing shows the correct sorting of the terminals.
Reopening the plugin shows the "old" sorting.
Also when i understand the source correctly, it should be able to click on some columns, and the elements should be sorted

But nothing happens, when i click or doubleclick for example XREF

i made a deeper dive into the source of the plugin

Within the plugin i switched positions with the down button.
Attached is example file and backup from the plugin created. Source is from here https://github.com/raulroda/qet_tb_generator-plugin

The upper part "update terminals" from the screenshot is generated within

    def update_terminals(self, data):
        """Changes the config of every terminal in the diagra. The changes made 
        in the plugin will be save in the 'elementInformation' of every
        terminal."""
        print('update terminals')
        for diagram in self.qet_project.findall('diagram'):  # all diagrams(pages)
            for element in diagram.iter('element'):  # all elements in diagram
                dt = [x for x in data if x['uuid'] == element.attrib['uuid']]
         

The lower part lists the tree withing "def save_tb(self, filename)"

It looks as if the properties of the terminals are switched (ground and standart) and not, like i hoped the positions within the plugin.
