Ghost groups after using the app

[Dragon31337]

I added a few groups and removed them later because two-way mirroring did not work.
After I removed all rules I still have few ghost groups:
Switch 1 and switch 2:
associationGroup1: [01]
associationGroup2: []

another switch I was not even creating rules for:
associationGroup1: [01]
associationGroup2: []
associationGroup3: []
associationGroup4: []

I wish there was an option to drop all existing groups.
