Reset Neo4j Browser style completely

I am unable to reset the browser visualization styles to the default grey colored nodes and relationships using :style reset in the browser. It seems to be setting it back to previous styles I have used for various nodes and relationships. For example, the nodes labelled "Country" which were styled in red change to green which I must have set previously sometime.

I also tried overwriting the styles with the following contents in a grass file to reset styles of all nodes and relationships but many of the nodes and relationships are still styled differently.

node {
  diameter: 50px;
  color: #A5ABB6;
  border-color: #9AA1AC;
  border-width: 2px;
  text-color-internal: #FFFFFF;
  font-size: 10px;
relationship {
  color: #A5ABB6;
  shaft-width: 1px;
  font-size: 8px;
  padding: 3px;
  text-color-external: #000000;
  text-color-internal: #FFFFFF;
  caption: "<type>";
