If you look at the editions for *Time-Marked Warlock* by Shami Stovall, you will see two copies with the same cover and one additional cover which does not look like the rest (dubbed the "ARC edition").
There should be two paperback editions, not three. ISBN 9781957613819 belongs to that ARC edition. ISBN 9781957613895 is correct, as-is.
Whichever is the case, superlibrarians cannot handle ISBN issues. You will need to contact support if you think the ISBN needs to be moved, though, as Scott pointed out, that is very unlikely.
