Weird problem after using multiman

I was playing thru some emulators and a few games via multiman 2.00 yesterday, when I exited the game to return to xmb, the icons for FBANext, Vice, Amiga Emulator and multiman have gone, only Gaia Manager and the disk icon remain, all else below have gone. I still have the option to install package files, do I have to reinstall or have I done something I shouldnt have? Basically, from the disk icon and below, only Gaia remains. I had Zen Pinball installed as well. Yesterday I installed package files to update the games I have on the HD, maybe one of these has a conflict?

Scratch that ive just noticed, all the icons are now under Gaia Manager! How did that happen?

PS3 will group the icons together after a while.

There is a way to ungroup, either triangle or square, can't remember off the top of my head

Same thing happened to me a few months back...confused the hell outta me at first! Seems the PS3 doesn't like too much clutter on XMB lol
