APA in Text Style

I have a confusing with Zotero APA style in text format.
In the first example, Zotero uses et al.: “Cetkin” article has three authors.
(Bejan & Lorente, 2011, 2012; Cetkin et al., 2012).
But in the second sentence, Zotero doesn’t use et. al
(Jolles, Boogert, Sridhar, Couzin, & Manica, 2017).
Why one example has et. al.and other doesn’t have?
Thank you
  • Likely because Cetkin was cited before. APA lists up to 5 authors on first citation but no more than 2 on every subsequent citation.
