Creations showing in my documents, but not in the game

Hi ^^.

I started once again to play to Spore and figured out that some of my old creations, which appaer well in "my creations" folder outside the game, don't appear at all in the game sporepedia. They are buildings, creatures, and i didn't use any mod to create them ; i really don't understand why they are missing from my sporepedia. Most of my old creations are there, but just a few of them don't appear.

Also, it's a bit strange, most of my old creations don't appear in the ingame "my creations" tab ; i can find them, but only if i seach them in the "all" tab where is all the content : the download creations, maxis creations, my own... For this point, it's not really a problem, but the fact that some of my saved buildings don't appear in game while they are in my documents is more anoying é_è.

I deleted the graphic cache and moove the pollination package in my desktop as said here : https://answers.ea.com/t5/Bugs-Technical-Issues/Spore-creations-not-showing-up/m-p/8008176#M10173

But the problem is still there, some creations which appaer in "my creations" folder outside the game are missing from my sporepedia. I really don't know what to do to solve the problem, so... i hope someone here would have more skill than me to know what happen é_è.
