I have a problem with the PLAXIS 3D model

Hi all:
I have a problem with the model, can someone please help me? Thank you.
I use PLAXIS 3D to create version elements to simulate continuous walls and buttresses (as shown in Figure 1). When I select buttresses and continuous walls for "intersect and recluster" (as shown in Figure 2), some version elements will only be represented by dotted lines ( As shown in Figure 3),
