Getting unwanted bottled views

One of my older videos started really taking of in the last few days. The views went up from few hundreds to like almost 60.000. At first I was happy but then I noticed there's no revenue, no watchtime, just views which come from India, Pakistan, Indonesia etc.

What could be the possible explanation for these views? Can I have problems with YouTube because of them? Is there anything I can or should do?

Anyone?
