It's a "flaw" from the 2.2 version of Xoops.

Just want to quote Skalpa here:

To clarify a few things: 2.2 is, technically speaking, a two years leap backward for XOOPS. It is not only a lot slower, but its architecture has also been greatly damaged in a way that makes it impossible to fix entirely.

Due to this, I can't display all the available multiMenu blocs on the admin side of the module. The only way to access them is through the block admin system of the 2.2 version.
