Ask the Experts / Hopefully a noob object question

Okay, I'm trying to set up a park in the scenario editor, and I have all my objects selected. However, a few of them aren't showing up in the object tabs when I go into the editor to try to build things. The ones I've noticed for sure are the two called "Wall-Graveyard©ToonTowner" which are half- and quarter-tile walls. There might be others missing, but I'm not sure. Please tell me this is a stupid problem with an easy fix.

By the way, I'm not using any hacks at all, so it's not anything of that nature. I'm running XP, if that makes a difference.

Thanks for any help you can give!

how many objects do you have in the ? tab if its 125 objects then you have to many selected with a tab for them so it wont show all the objects.

Yep, looks like that was the issue. Thank ya much!

in other cases it could help if you open the park with parkdat and click update headers and save it again.
