Tech challenged, no time! And there's SO many posts to read. I know this will be a simple fix for you Calibre gurus.

So please, be patient with me.

I set up my Calibre library ages ago. Recently made some changes and now messed up my plugboard for sorting metadata on my Kindle and phone [Samsung, same azw3 library].
I would like my book information to read like this;
authorlastname_firstname - series - 0.5.5
[title would be great after this for additional sorting on my phone app]
However right now I'm getting this;
authorfirstname - series 05.5 authorlastname
plugboard template is this right now:
{author_sort}{series:| - | }{series_index:0>4.1f} - {title}
I know I messed this up when I deleted my Sony settings [no longer have it].
Really appreciate the help, I know it's a simple thing for you tech savvy people, not for me though.
Thank you in advance!
