Have you considered using point features for your layer with an
attribute for diameter? You can then symbolize with a circle scaled
to the diameter attribute. This doesn't answer why you're getting
diamonds, but gives you the map you want.<br>

QGIS version 3.1.8
I have a shapefile I'm working with, showing the locations of a number of what are called "post molds" - evidence that a post was put in the ground there at one point. I've drawn circles for each post mold, but they're all rendering (showing) as diamonds - squares rotated 45 degrees. Other shapes also are not rendering quite as smoothly as drawn (freehand).
I cannot figure out what is causing this (the wrong shape for the circles). I can draw ellipses and they show up fine. I'm really reluctant to try to redraw any of the existing ones - there are several.
The map itself covered an area of about 50 meters by 50 meters. The circles are all in the 2-5 decimeter range (approximate).
Also, is it possible to re-size an existing polygon - for instance make an ellipse larger than the original?
Thanks!
Bob
