Hi @listin
Welcome to the Quick Suite community!
Quick Suite often drops columns during S3 CSV ingestion via manifest when parsing fails due to inconsistent delimiters from consecutive commas (empty fields) or complex formats like timezone offsets in timestamps.
Remove textqualifier entirely, as unquoted CSVs with consecutive commas can confuse quoted field handling, your sample data lacks quotes around values. Add selectColumns to explicitly include all 59 column names from the header, forcing to parse them.
Please refer to the documentation and community post below, as it may help resolve the column parsing issue.
