Why are cart attribute details not appearing for existing customers?

Hi there,

I have three cart attributes (date picker, time and message card) which is suppose to appear in the admin orders additional details section. However, it only works once per customer. So this may seem weird but I will not get any additional details from existing customer but for new customers, it works fine.


       
    
  

 

      
   	  
    


  

  

I searched endlessly to find if anyone has the same problem but to no avail. I really appreciate if anyone has a solution . Thank you .
