price update problem,

Hello, good plugin, but I have a price update problem, I tell you
1- when I import for the first time, the product increases the price according to the configuration (ok)
( from 0.00 to 6.00 Increase by Fixed amount ($) 2.00 )

2- when the price changes on aliexpress, the plugin updates the price incorrectly

the plugin updates and increases 4.80 more, instead of only 2.00

I suppose that in all the items I will have the same problem … 🙁
