Error in RM Editing Events

When I try to edit any existing set of Trigger Events, I get an "Unexpected Error" page. When I look at the logs, I see this error:

2020-09-06 07:28:22.385 pm [error]( java.lang.Integer cannot be cast to java.lang.String on line 873 (selectTriggers)

I'm stuck. Any idea how to get past this error?

Sometimes it’s easier to recreate the rule than to solve the error 🤷

Show a screenshot of the rule. Screenshots are much easier to use than copy/paste.

I deleted them and started over. I tried different things and I noticed they were all copied from another rule and modified, not sure if that was the problem. The ones not copied worked as expected.
