Multi level list with bullet point/number

Hi ,

I am using AEM 6.1 and I have requirement to create multi level list with  bullet points/number in RTE. I am using indent/outdent  and creating list. Issue is after one level of bullet circle point I am not able to use circle bullets again in second level , it will convert circle into square bullet.

I am trying to achieve below list in AEM RTE but I am not able to convert square bullet into circle bullet after first level

1. heading
   • subheading
   • subheading two
     • child one
     • child two
       1. sub child one
       2. subchild two
          • grandchild one
          • grandchild two
