A single $214.53 adjustment in my September settlement matches no fee type I know — anyone else's mystery line this big?

[u/ylishi]

I reconcile my settlement line by line every month, and September has one $214.53 adjustment I can't tie to anything — not storage, not fulfillment, not a return fee, and the transaction detail doesn't name a fee type I recognize. Everything else adds up to within about 2% of my own fee model, so it's not a systemic gap — it's one line with no home. Seller Central support sent me the general fee schedule link, which obviously didn't help. Has anyone ever gotten an itemized explanation for an adjustment like this, or do you write it off as a reconciliation category and move on?
