It is normal for the interface not to show up in the olist of a (S,G) entry in the PIM topology table as per the following documentation excerpt:
"For example, an interface is added to (*,G) entry in PIM topology table upon receipt of an MLD report or PIM (*,G) join message. Similarly, an interface is added to (S,G) entry upon receipt of MLD INCLUDE report for S and G or PIM (S,G) join message. Then PIM installs an (S,G) entry in MRIB with immediate olist (from (S,G)) and inherited olist (from (*,G)). Therefore, the proper forwarding state for a given entry (S,G) can be seen only in the MRIB or the MFIB, not in the PIM topology table."
