Remove Rule with error

How can I remove a rule that is bugged. The rule details will not show - including the remove button.

error in log:
[app:329] 2018-06-13 09:06:15.924:errorjava.lang.ClassCastException: null (mainPage)

In the list of rules, click the "i" in the blue circle to the right. That with show you a status page for that rule. Next, scroll to the bottom and click "Remove App". That will remove that single rule, not the whole Rule Machine app like it sounds

Thanks. That worked.
