DBZ, episodes missing????

I downloaded the first 4 Digital Remastered Dragonball Z Sessions, ending with
Dragonball Z - 136 - No Match For The Androids
I wanted the rest, so I downloaded the normal episodes, but the next episode is called
Dragonball Z - 122 - Last Ditch Effort

From 136 to 122, why?

Is the story of the Digital Remastered DBZ somehow longer?
