Facebook Purchaese not matching Shopify

[KitchenPower]

Hi, 

My facebook Pixel was working very well till the last few days. My shopify and google analtics says there are a conversions coming in from Facebook. But in Facebook none of my campaigns is showing purchase events. This is the only marketing campaigns i got running so these conversions are coming from facebook. The pixel is working because Facebook shows that purchase event is working. There are just not linked to the campaigns. Screenshots below.
