I have been talking to Angela about the subscription. Do you not have access to the premier subscription because you are not the owner but the developer? You should be using current versions of POWER and EXPERIENCE Add-ons. They are both 4.7.1
The LEGACY versions are not being updated and the individual add-ons will not be updated. Your screen shot shows all old versions that are part of Power (ProPAck, Directory Builder, Pages ) and Experience (Enhanced Results, Enhanced Search, anything Enhanced and Widgets) Please discuss with your client.
