I have found 2 conflicted orders for the episodes of this series.

The one listed here that is given on the following page :

• Wikipedia US : https://en.wikipedia.org/wiki/Jana_of_the_Jungle#Episodes
• Big Cartoon Database : http://www.bcdb.com/cartoons/Hanna-Barbera_Studios/G-J/The_Godzilla_Power_Hour/Jana_of_the_Jungle/ and http://www.bcdb.com/cartoons/Hanna-Barbera_Studios/G-J/The_Godzilla_Super_90/Jana_of_the_Jungle/

Another order given on the following page :

• IMDB : https://www.imdb.com/title/tt0190911/
• TheTVDB : https://www.thetvdb.com/series/jana-of-the-jungle/seasons/all
• Hanna-Barbera Fandom : https://hanna-barbera.fandom.com/wiki/Jana_of_the_Jungle

I am not able to find an official site for this series, so I am not able to say which one of the 2 orders is correct and which one is wrong. I only mention the existence of the 2 lists for reference.
