Beelovy review for SB: Facebook Pixel and TikTok

I use this app very well for many stores, but for this store, I installed the app but it could not send only Purchase event to Facebook (other events like view content, Checkouts Initiated, Add To Cart... sent normally), I know it because It shows result Checkouts Initiated, Add To Cart... in Facebook Ads Manager but always empty with column result for my campaign with Sale Objective . I sent email to support but not any reply. Please check my configuration and help! Thanks!
