p <- p + geom_text(labelMap, tiplabDT, size = I(text.size),
hjust = -0.1, na.rm = TRUE, show.legend = FALSE) #added show.legend=FALSE so that the legend does not show colored "a"s when using plot_tree.

When using plot_tree with tip labels and a color, the legend is altered and colored "a"s appear. I tried removing these after executing the plot_tree command but was not able to. Instead I needed to edit the plot_tree function itself to add "show.legend = FALSE" in the final section.
This removes the geom_text "a" from the legend.
This image shows the "a"s in the legend:
Here is what a similar tree looks like with "show.legend=FALSE" added for the tip labels:
p <- p + geom_text(labelMap, tiplabDT, size = I(text.size),
hjust = -0.1, na.rm = TRUE, show.legend = FALSE) #added show.legend=FALSE so that the legend does not show colored "a"s when using plot_tree.
