Sims 4 DLC not working

Ok, fixed it.

@blue_lily_208_27  I'm sorry, but this is still not what I need.  You've run the search correctly, but you didn't expand the window to show the full location for each entry.  This is what I need:

You might need to expand the Folder category, perhaps by dragging the | to its right.  The reason this is important is because I can see that at least one copy of EP11 is in the wrong location, but I can't be sure the others are in the right place.

Ok, I think I fixed it.

@blue_lily_208_27  It looks like you have an extra "The Sims 4" folder directly on C.  What's inside this folder?  If it only contains DLC folders, for example EP11 and EP14 (it definitely has those, at least), please delete this folder.  If you get an error, restart your computer and try again.  You can reach this folder by clicking This PC, then double-clicking the C drive.

Once you've done that, go here:

C:\Program Files (x86)\Steam\steamapps\common\The Sims 4

Delete the EP11 and EP14 folders inside, then open the _Installer folder, and DLC inside that, and do the same.  Restart your computer again, clear the EA App's cache (again):

and download the two packs again.  Let me know whether any of their content shows up in-game: the worlds, the objects, the CAS items, whatever you can find.

I did it all and went on the game again. It's still not working. But I did find this.
