Solved
Spore creations are not sharing to Sporepedia.
The button says they're shared but the in-game comments, etc, to the right of the creature you're viewing, doesn't load either.. logging back in, refreshing, uninstalling and reinstalling didn't work...
I ended up following this solution https://steamcommunity.com/sharedfiles/filedetails/?id=582350678 to "migrate" the Spore game and addons into EA's Origin app - which worked for me
Thankyou anyway for your response :} I appreciate it
