Order of the indicators in WingPanel changes every time I restart the computer

[Thulium Equasman]

Different indicators in WingPanel like User Accounts, Language bar, battery indicator, Sound menu, message indicator and Switch off have their particular order, I assume. But every time I restart the computer their order of appearance changes. Like in an order the User accounts may come first whereas it might appear last in another restart.
