First time we see the use of the Dragonzord without Tommy (Green Ranger). Although he gave his remaining powers to Jason, there is no explaination of his disappearance.
When the 2nd time the rangers teleport to the command center they are wearing different outfits than when they teleported the 1st time before they battle the monster and morph and in the scene before.
Jason Frank is removed from the opening credits with this episode and - despite still being friends with the rangers - strangely disappears from the show until he is once more given ranger power.
