Is Events and scipt combination realible?

I encounter a weird issues, I already breakdown all the events and code multiple times, debug the parts one by one and still can't figure the issue.

The event is pretty simple:

Sometimes the array added is 11-15, even the Construct repeat event is only 10.

This issue may related to my code, but I just want to make sure, is I use the event combined with js code the wrong way?
