title: Buffer within QGIS not working properly
body: <p>I'm an R Programmer but I found that Qgis is better for some geo projects.  I'm having a tough time with something and I've searched.  Basically, I want to create a buffer around 5 points so that I can then sum the population for the buffer area.  The issue I'm having is that the Buffer dropdown is not in my Geo Processing Tools.  Rather I have a Fixed Buffer (QGIS v2.18.14 mac).  When I use the fixed buffer I get a gigantic circle that takes up the whole map.  Any ideas where I might be going wrong?  <a href="https://i.stack.imgur.com/eUU5U.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/eUU5U.png" alt="enter image description here"></a></p>
