Aliexpress : Product diagnostic "poor title" / synchro with prestashop

[Isma B]

Hello, I am looking for any person using Ali express official module with their store prestashop v.1.7.7.7 , lately we noticed that we are lacking visitors and orders from customers, I would need some advise / guidance :

Product diagnostic of A.E shows all my products with poor titles / too short , I have amended on prestashop but as syncro with A.E may take several days, I will also amend several products manually (and also add some characteristics, marketing pic)

My question : when products will finally synchronize with my store, will the amendments made on A.E manually be affected / canceled?  

Thanks in advance for your help
