Help The objects within the two solvers do not collide with each other.

Hello.
I’m currently working on a project using Obi Cloth and need some help, so I'm reaching out.
The structure of the objects is as follows:

1. Objects with fixed update
   
   2. Mesh 1 with an Obi Collider set
      
   3. Game object with a solver applied
      
      3. Object with skinned cloth set
         
   5. Game object with a solver applied
      
      3. Object with skinned cloth set
         

As shown in the attached picture, the structure is like this. The two solvers are managed within the fixed updater.
The issue is that the upper object in the GameObject and the lower object in GameObject (1) do not collide with each other. Is it possible to make the objects within these two solvers collide?
It is unavoidable to split into two solvers because I need to adjust the scale for some objects. While the solvers are separated, can we still allow for physical interactions between the objects?
Thank you for your support, as always.
