Problems with export customer base

[LCPT 0]

I exported my customer base to modify their point balances, then imported into loyverse. However, there is no data in the column "Purchase amount" of my clients. My CVS file is correct, even I imported the backup file but "Purchase amount" is always 0 or a random number.

When you are importing is better to not upload a big number of customers. Also is recommended to use a template for the customer database (the first 6 columns can be edited) Customer ID, Customer name, Email, Number, Points balance, Note. Only these 6 columns can be edited.
