This forum is not the primary location to report bugs or make feature requests. It is totally the right place for asking if something is supposed to work this way, is happening to other people, or discussing them before reporting, etc.
The best place to report bugs or make feature requests is on our github repo, which you already found if you installed nZEDb ;-) The issue tracker there is used to track stuff. i.e. if it's not there, we probably don't know about it ;-)
When creating an issue there, please also tag it with BUG, FEATURE or other appropriate tags to make it easier for devs to spot.
