"One end product", but 2 versions of it

Hi there!
I’ve realized the past year a video for a client of mine. The video include 2 different audio tracks (that I call for conveinence track A and track B).
Now the client ask me to do 4 different versions of the video:

  • Track A + B ver. 1 (the original one)
  • Track A + B ver. 2 (but with a different line of text at the very end of the video, I literally mean 2 changed words)
  • Track A ver. 1(only the first part of the original video)
  • Track A ver. 2 (only the first part of the original video but with a different line of text at the very end of the video, I literally mean 2 changed words)

Track B isn’t from Audiojungle, so we’re talking only about Track A: do I need to purchase another 3 licenses for the Track A?
Thank you so much for all the replies
