If I see the Flow condition correctly, you are using AND function for both WS Status = Pending, complete and FS Status equals Pending, Complete, which will always trigger on both conditions, because it even meets when WS is Complete, but FS is pending, and vice versa.
You might want to put condition like-
-> AND WS Status =Pending FS Status= Complete ->And WS Status =Pending FS Status= Pending
If Yes, Send email for WS status
or something along these lines based on your requirement. I also see another condition above this in your screenshot, so not sure if that as well sends an email.
