Batch Presets and EXIF Data

[MadMax1412]

Hi

2 related questions.

I created a batch preset and realised I forgot to go in and select the options to include the Metadata, so I created a new batch preset as I couldn't figure how to edit the one I created. In my new preset, I selected all the options under Metadata but I noticed that the data for "Authors" is deleted. In my raw file (ARW file from Sony A6400), the Metadata is there (ie my name as set in the A6400) but isn't in the JPG output.

So my questions are:

1. How do you edit a previously created output batch preset (or at least delete it); and
2. How do I get the "Author" part of the metadata to be kept?

Thanks in advance.
