Oil Rings on Rock Shox Deluxe

I have a RockShox deluxe select + on the rear of my Epic Evo 7. I did the Rock Shox recommended 50-hour service back in October and have only ridden the bike another 25 hours since then.

Just last week I started noticing rings of oil on the shock. The attached photo is what it looks like after and approximately hour-long ride.

Is it possible I overfilled the shock with oil and this is the excess oil working its way out? Or are the seals bad and I need to redo the 50hr service with new seals?

If it’s dripping a huge amount the seals are gone but a bit of residue is okay. Just give it a wipe down after each ride.
