This happens to me too. The icon and the rep bar for the current active faction are always shown correctly, but sometimes no text appears beside the icon.
Same problem here. Switching Text off/on helps.
Same here - also, quite often the setting for showing the rep bar is lost - I might have text, but no bar. Again, toggling the setting (in this case, show rep bar) off and on fixes it.
Is this actually being maintained any more or should I start hunting for an alternative?
