I would let the Clerk know what I found and then leave it up to the Clerk to decide.

I've always had an excellent, friendly working relationship with the Clerk, Assistants and "town" office officials - many years in real estate and as a title searcher (those old handwritten, pre-typewriter and photocopier searches).  I've found wonky index references or luckily after they were scanned but before proofed and returned, deeds where the bottom inch (which included some "subject to" clauses) were cut off [sheer luck & experience, I knew the property and it didn't look right, so I asked to see the original].

 I politely told the Clerk what I had found or pointed out, "Gee..." quietly in a nice tone.  Sort of a, "did you know" or "did you see."  I even state, "this isn't a complaint, but ..."  Said when NO ONE around the Clerk can hear.  Each time the Clerk was VERY GLAD to hear this, particularly as I wasn't nasty about it.  They can't always "correct" some things, but I'm not the document police. Sometimes, it's just the way the "database" works (like male Smith-Jones is Smith Jones because the system doesn't allow "-" to be entered; Smith-Jones was indexed under Jones and will always be - not fixable and recording party didn't include a note, "please index under "Smith Jones").

Result:  Good working relationship and when I walk in with the occasional "oops," the Clerk taps her finger on the spot and then I walk away to see what's up before the oops gets permanently recorded for all the world to see ... and needs to be fixed later.

As all the feet-on-the-ground people know, there is a good reason to have some human face-to-face contact with recording offices and actual paper documents. As we all know, you can learn a lot in a 60-second conversation from friendly recording clerks. Or, like above where luckily the attorney who prepared the document had a paper copy with the recording information still in his file - and SHARED it.
