I hope this is the right section from whence to place this problem. Here goes anyway.
I read my first book in Calibre. When I finished reading to a certain point, I clicked on the "Book Mark" icon within Calibre, then the bookmark label so I knew where to begin from when I next wanted to read from the book again. It worked flawlessly on the first book I read.
I started reading a second book and every time I bookmark this particular one, when I revisit the book, it opens up miles upstream from the bookmark I chose.
I have tried resetting from a particular chapter to see if that would rectify the problem, but it hasn't.
Now I have to make a mental note where I last left off from the book because the bookmark never takes me to the right place.
Any ideas where I'm going wrong here? Why did this function work with the first book and not the second?
