First of all the faces are still training, perhaps previous src had bigger/slanted eyes so in some shots it's still visible and causes eyes to go all wonky. Or maybe you have some faces in src that have motion blur from camera rotating/moving up/down so it makes eyes look like that? Most probably it's bad alignment but certainly odd one as usually src faces train properly even if they are not aligned (predicted faces in 2nd row always look no matter what).
Try to get a new dataset and run it with that model again or try out other dataset you know works and see if the eyes also look odd.
Use SF3D if you hadn't used it for aligning your src. If you have random ct enabled during training disable it. Make sure you align src with the same DFL version you are training (newest one).
