Another option is to abandon the current spikes & ferrules and use brackets:

There are many types to choose from. A couple of examples are these
internal ones:

When I had my gutters replaced a few years ago, they got rid of the
spikes (which were doing what yours are doing) and used the
internal brackets.

The internal sure look better. Less fasteners; thus, less chance of
opening the wood to water exposure. I guess caulk could be used to
seal the external bracket screws from water intrusion, via caulk in
the holes of the fasteners before mounting.
