I contacted the elementor pro support, they said this might be caused from other optimization plugin. But acctually I don’t use optimization plugin much and Already disabled all options that might cause this problem. So I will keep contacting them.
On Xstore’s end, if you think this problem might be cause with your render process or option, please let me know.
I will keep posted once I have update on this issue, thanks!
