CSV exports from the Query widget in ArcGIS Experience Builder Developer Edition v1.18 do not preserve the original field order as defined in the data source, resulting in inconsistent attribute sequencing in the output file.

Workaround

1. Open the feature layer in Map Viewer.
2. Click Properties and expand Information if necessary.
3. Click 'Manage layer properties' > 'Reset to source layer properties'.
4. Save the web map.
5. Perform an export in the Query widget of ArcGIS Experience Builder.
6. The fields in the exported records are displayed as expected.
