Issue with CSV Feed Generation After Recent Update

I am writing to report a problem with a CSV feed generation plugin that we use in WooCommerce to export product data to Facebook. Following the recent update of the plugin, we have encountered an issue where if a field (e.g., color) is empty, the plugin skips this field entirely in the generated CSV file.

This behavior causes a misalignment in the data, as the skipped fields disrupt the matching of data to the corresponding column headers in the first row. Consequently, the exported data becomes jumbled and does not accurately align with the respective columns.

This issue significantly impacts our ability to correctly export and use our product data. It would be highly appreciated if you could investigate this problem and provide a solution or workaround. We rely heavily on this functionality for our Facebook product feeds and are currently unable to proceed as usual due to this issue.

Thank you for your attention to this matter.
