No worries. It's probably referring to this part of the licence:
"A Licence does not allow the Purchaser to:
(b1) Use, sell, share, transfer, give away, sublicense or redistribute the Licensed Asset or Derivate Works other than as part of the relevant Media Product; or
(c1) Allow the user of the Media Product to extract the Licensed Asset or Derivative Works and use them outside of the relevant Media Product."
Essentially, don't include an accessible zip or archived version of the asset pack available within your project for others to extract and use.
