Hello,
Can you please try using Discovery to see if the shared topology is successful and take into FM?
In SpaceClaim, apply force share as well to see if there are contacts that have been missed with the set tolerance. You can always vary the tolerance to see if additional contacts can be picked up for shared topology. Also, use the repair tool for split edges, inexact edges and small faces to make sure geometry is free of these as it might affect the ST.
