Referencing to a default file

[domer1322]

need some help .... I have a file that doesn't refer to default files.  Specifically, when I open a plug in object for a door, then select hardware, then try to apply a hardware set, the normal options are grayed or empty, and there is no reference path to the default file for door hardware .... nor is there any option to pick the default file.  This only happens on this file, so the other files on my computer refer to the default hardware file just fine.  How can I fix this ?

Is the plug in object styled? If so then perhaps the hardware settings are per style settings so you won't be able to change each instance of the style individually. If this is what is happening try editing the style and toggling the hardware setting from per style to per instance. This is a snapshot of my title block style settings:
