Potential Solutions:

1. Adjust your file naming convention Consider using a naming pattern that ensures proper alphanumeric sorting, such as:
   • L01, L02, L03... instead of L1, L2, L3
   • Adding leading zeros ensures consistent sorting regardless of how many files you have
2. Upload files one at a time in the desired sequence While more time-consuming, this might preserve the order better than bulk uploading.
3. Create a custom section for displaying attachments If you have development resources available, you could create a custom section that displays attachments in a specific order based on their filenames or other metadata.
4. Check attachment metadata Pega might store metadata about when each file was uploaded. If this is accessible, you might be able to use it to sort attachments by upload time.
5. Contact Pega Support directly Since this appears to be a specific technical issue with attachment handling, I recommend creating a support case with Pega Support. They can provide more targeted assistance based on your specific Pega version and implementation.
