Unfortunately it could also be that the ground coffee is of inconsistent fineness with both course and extra-fine particles present at all grind levels.
My Rocky did this before I modified it with plumbers tape, etc., so I would suggest you investigate what options are available on your grinder.

Re: grinds
Also do you flush out group head between shots, have a look and see if you can see any stray grinds up there.

Re: grinds
Do you wipe out your filter basket before you dose?
Maybe inconsistent grind of the i-mini?
