Combine book listed twice in same series

[J.]

Hi, the second book in my series is listed twice because the series is worded differently in each title. I'm not sure if they need to be combined or the second one deleted. (#1 link below has the series name matching the first book in the series, and also has a couple reviews.) Thanks for the help!
