Imported Product price appears to high than Price from Ali Express after sync it

Hi, i already comment under a other thread about my problem i use the newest version of the extention (1.2.7.6 ver) and wordpress plugin dev version.
after sync the prices it will increase the prices much too high or does not update them on my import list… if i manually sync the product

Also every product combination is on sale but the plugin or extention (1.2.7.6 ver) just import it randomly some are on sale & some have not even a regulary price…

now with the dev plugin the product page does not even work anymore for the imported product…
