Amex (BA Amex) transactions syncing to Google Sheets with blank Account in column A

Hi — loving the tool so far. One issue on a fresh Google Sheets destination (Overview Template):

Most rows populate Account correctly, but a block of American Express (British Airways Amex) transactions is syncing with column A (Account) blank. The rows are otherwise complete — Date, Amount and Payee are all present (e.g. Toolstation, Ringgo, Monthly Membership Fee).

What I noticed:

• The labelled Amex rows are dated June 2026, then from the first blank-Account row the dates jump back to Dec 2025 — so it looks like a separate slice of Amex history being appended without its account name.

• Enrichment is off; other accounts (First Direct x2, Santander, Barclaycard) all label fine.

• Connection itself shows Active and is pulling full history.

Possibly related to Amex supplementary/second-card handling? Happy to share screenshots or a sheet sample if useful.
