In AppSheet PDF templates, mixed or repeated child records usually happen when the <<Start>>/<<End>> expression isn’t properly scoped to the parent row. In your HTML template, make sure the child table loop references the parent’s key explicitly, for example:
<<Start: [Related Loan Sheet]>>
<<[ColumnName]>>
<<End>>
```
If you’re using a `SELECT()` instead, filter it with `[_THISROW].[UID]` so only matching child rows are returned. Also confirm the Ref column is set correctly in the Data > Columns tab so AppSheet generates the reverse reference list automatically.
