+1 on what Sabii said.
I've had comments added and removed (and other minor, odd changes) to my student loans, and CK/other FAKO score sites always show the score jumping around. I'm not going to say that Vantagescore is never used, but it rarely is, and while my VS scores hopped about, the FICOs were very steady and never showed those odd comments/changes.
If you're curious, you can go to Experian.com and do the $1 7 day trial (just "downgrading" your membership to the free version before the 10 days is up) and you can pull FICO8 from all three big CRAs.
oops! Apologies - reading comprehension fail
Sabii is right, though, remarks won't change your FICO score. There must be some other change.
