The surface for INTERFACE_SSI_STATIC should match that of INTERFACE_SSI. If you use OFFSET in one, use it in the other too.

Also, there is no need to specify a single-element DRM layer - the effective seismic input in LS-DYNA follows Bielak's earlier papers, not the later ones. The only requirement is that the PML should be at least two elements away from the INTERFACE_SSI

Possibly, even in the dynamic case, the meshes on either side are not separated (you should see duplicate nodes on the interface when you highlight it in LSPP)
