wrong dispatcher filter rules for role my-aem-dispathcer

I created a role my-aem-dispatcher which extends role aem-dispatcher and add a filter rule. by default there are 10 filter rules. but after i change the dispatcher rule to my-aem-dispatcher in the environment definition. I got 12 rules.

Hier are the example code

the generated dispatcher filter rules are:

filter with index 0 and 12 new added. But rule 0 { /type "allow" /url '/.*' } is wrong.
