sales price during cron update setting to 0

We put some items up on sale on our variable products, during the auto update it resets all our sales prices back to 0 again. Note we are only putting certain items up on sale not all. Even after switching off:

Update price Update price of WooCommerce product if price of respective AliExpress product changes. All rules in Product Price tab will be applied to new price.

In Product updating when it auto-update it still changed the sales pricing to 0. I am a paid customer of this plugin. Please advise soon as this disrupted my live store sales products after update.
