List of girls with typos in their information:

->Open Spoiler<-

Hiyori Katagiri (SR) is the correct name, not Hiyuri Katagiri.
Hotaru Natsume (SR) is the correct name, not Hotsume Natsume. (Even though that is hilarious)
Misa Fukawasa (SR) is the correct name, not Miss Fukawasa.
Noriko Takase (R) is on the list twice and is taking a spot that Shiori Honjo (R) should be in.
Saki Kakiuchi (SR) is the correct name, not Siki Kakiuchi.
Shizue Kitano (SR) is the correct name, not Shiue Kitano.
Suzuna Hanamiya (R) is the correct name, not Suzana Hanamiya.
Yui Takami (SR) is the correct name, not Yui Takama.

Also I looked up the girl Chitose Sakuragi (SR) on Google by her name in Japanese (桜木ちとせ) which led me to a website (セイジオンライン体験記　R18 : ペロペロ催眠　親衛隊イベント　と� �る学校の部活勧誘) that had her picture and a description of the event. I ran this through Google Translate and found out she is part of the event and although I cannot decipher what is said completely, it should be related to an EP reward. I can only think of this being a reward for getting EP from ultra guards which was the second part of the event that we didn't really get. Thank you for giving me the Japanese name or we wouldn't have found out about this.
