Usage of regular vs sales price during auto-sync

Hello,
I have the pro version, it is working great.

But I have an issue/question regarding the automatic price calculations.

So for example I have this product that was auto-synced last night:
https://bigcupofcoffee.com/shop/portable-cold-brew-coffee-maker/

Here is the Aliexpress product:
https://www.aliexpress.us/item/3256805322711910.html?gatewayAdapt=glo2usa

As you can see, the aliexpress one has a sales price. The synced price to my site is the correctly calculated price, but it doesn’t show as a sale price, rather as the normal price.

I would like to show this as a sale price, with the normal price sync-ing as well. I think this is set in the Product Price tab in the plugin settings, where I have a formula entered for both the sale and regular price.

But it’s not working.

Thanks
Tom
