Can't display fusion footage properly?

After I've made special effects on the fusion page, I won't be able to display the picture completely. Any special effects are the same. After I return to the clipping page, I will have this kind of situation. The previous version will not be generated. Is this a problem?

I waited for three days. Why hasn’t anyone answered?

Turn your proxy mode off for now.
We will investigate for a future beta.

OK. Thank you for your reply
