title: why are there colors and comparisons missing?
body: <p>I'm using this command via <a href="https://indrajeetpatil.github.io/ggstatsplot/articles/web_only/ggbetweenstats.html" rel="nofollow noreferrer">ggstatsplot</a>:</p>
  <pre><code>ggbetweenstats(
    data = df_sub
    , x = Generator
    , y = hours
    , outlier.tagging  = TRUE
    , map_signif_level = TRUE
    , ggsignif.args    = list(textsize = 4, tip_length = 0.01)
    , results.subtitle = TRUE) + 
    theme_bw() +
    guides(fill=guide_legend(&quot;Class&quot;))
  </code></pre>
  <p>and receive this plot:</p>

  <p>which is fine, except that those three group levels to the right are missing data points and colors. In addition, some statistical comparisons/tests are missing, or? E.g., the one far to the right is compared only once.</p>
  <p>I cropped the image slightly as the data is confidential.</p>
