Are settings in an external bpatcher saved in the pattrstorage root patch ?

Hello,

I have a patch that embed several instances of the same bpatcher with a grid inside. I can see in the pattrstrorage the pad on and off but when I save the patcher and reopen it this settings are not recalled.

I have named the grid with "#0-grid" but this does not work too.

I tried with an embeded bpatcher and the grid is properly saved and reloaded. But apparently not when the bpatcher is created outside.

Is it normal ?

this is the working patch:

The one that does not work is bigger. So I am not sure I can copy it but this is the subpatch I try to embed:

I guess the problem is that I try to have several instances of this last one in one single patch. Let me know.
