No reason to contact google.

An invalid click does not mean YOU did something wrong.

Invalid clicks are normal and happen all the time.

They happen for a variety of reasons, like accidental click,
clicking out too soon, etc.

Images probably get more accidental clicks than text.
Sometimes a click sends the person to an offer for
completion, and they must complete it. Like filling out
a form.

Invalid clicks don't get you banned. Click fraud does.
Clickfraud is not getting invalid clicks. You accidentally
clicking on a link is an invalid click, but that won't get
you banned either. One day I know I accidentally clicked
5 times, dang it.

Now before people explode, there is a ratio. If the majority
of your clicks continue to be invalid, and that's rare for
normal people, then they may disable adsense on the site.

Disabling adsense on a site is not a ban either. It happens.

Thanks paul. Appreciate the reply. I checked my ad types and it appears this click is for a flash ad type. Ive only had 8 clicks this is my 8th. Still new to adsense.

Good to know an inactive click isn't a sign of danger to come working hard on my sites.
