product pricing

Good afternoon;

1st Problem: I’m having problems in pricing the products, when he imports the product he correctly brings the value of AliExpress but when converting to BLR (R$) it converts to the old value of the site, and does not respect the value with the discount that the site is giving, so my client ends up not having the discount, and will pay for the amount without the discount, see the attached prints.

2nd Problem, it is in the synchronization of products automatically scheduled 1x a day, it only synchronizes 35 products and today I have twice as many products, the system only synchronizes all products when I click on the button: Product synchronization, then it synchronizes them all.
