Hi, I am new to Calibre and although I've tried several times after installing the Collections plug-in I just can't work out how to get my books into simple collections by Author. Some are how I'd expect but for instance, I have 75 books by one author, some show up in a Collection with the authors name and a lot of others are shown as separate collections with just one book in each. How do I set it to put all books by the one author in a single collection? I'm sure it should be simple and I'm just not clever enough to understand all the options.
Sorry if this is a really basic question
