- By logic of the guidebook, the listed ages on character pages are ages at the start of season one when Shiro returns to Earth: the book claims that Pidge was 14 when Shiro was first captured along with the Kerberos Mission crew while listing her actual age as 15. This coincides with the passage of a year between Shiro's capture and his return to Earth.
- Series staff Joaquim Dos Santos and Lauren Montgomery have expressed concerns that published merchandise may take information from the show "bible" or "original pitch", but their ideas have changed organically over time, so information may not be accurate, and they did not review the book for errors before publishing.
- Josh Keaton has stated that during production of the show as early as the voice actor auditions, the pitch was "five teenagers", but certain character models ended up looking different than the description, so the writing adapted to the finalized designs. This suggests the book does not take the ages from the original pitch as staff feared and reflects the organic changes they have made, because it publishes Shiro's age as 25 and not a teenager in contrast to the original pitch published on merchandise.
- The ages listed in the guidebook generally match the ranges given by Montgomery and Dos Santos at San Diego Comic-Con 2016. The heritages listed for Lance and Hunk are consistent with statements by their voice actors.
- Staff has officially revoked support that Keith's liking of hippopotami, suggested by the guidebook's quiz, is canon.
- Despite the contents of the book including only the first two seasons of the TV series, Lotor appears on page 49 as a teaser for season 3.
- The book erroneously uses a picture of Rax in place of Shay, whereas Rax's own picture is of another Balmeran.
- The coverage on the bayards was contradicted in season 3. Whereas the book states that a specific bayard was used for different styles of fighting, the TV series show that they adjust to the whichever paladin is using it.
