Addon tab for key not showing

Downloaded time.ly Version 2.3.4 using native WordPress plug-in installer.
Bought Core+ doing install of CSV addon: downloaded from timely Version 1.0.5.2
Uploaded/installed using native Word press tool for zip files.

Site documentation step-by-step’s show the following #2
http://time.ly/document/user-guide/getting-started/install-add-ons/
notice the addon tab

My installation shows a different setup:

no addon tab

The addon submenu leads to buying links:

I need to do this for all the time.ly addons in core+

Please advise.
TIA
