This should not be the case.
To find out whether this is being caused by the unit itself or your electrical installation
I would try the device in different locations.
If you bought online and are able to return the unit, I would proactively try to ask for replacement
before this possibility expires.
Make note about the serial number to see whether you get another unit back.

static "shots" are usually caused by increased electrical potential discharges from air being caused by air being too dry,
this is usually problem during winter when because of heating air humidity drops, you can measure if your room humidity is less than 40% as such condition isn't good for any electrical devices

This is not about 'static shock' or humidity. It's about a constant flow of leakage current to ground. And if no ground is connected the human body is the way the current travels.
