No, this shouldn't happen. Note for device tree based boards you should turn off CONFIG_CONSOLE_ACTIVATE_FIRST as the console will be activated by the /chosen/stdout-path property. With CONFIG_CONSOLE_ACTIVATE_FIRST enabled it can happen that the first to be registered console gets activated by this option and another one from the /chosen/stdout-path property. Maybe this is your problem already or are really all four consoles activated?
