Once you put the file in there you can change the output settings (or drag and drop other settings onto it). Are you not able to change the settings once the file is in AME? All the yellow text provides contextual menus that you can change as needed. Drag and drop from the Preset Browser also works.
Yeah….that's not right. Sounds like you may need to clean your cache (preferences --> Media --> Clean Media Cache). This may also be a deeper problem that requires a uninstall/reinstall of the software.
If you're on Adobe Creative Cloud (CC) then the process is a breeze. If not, you'll need to find your disks and de-authorize your software, uninstall, restart, and then install fresh copies of Adobe.
