In Highcharter, how do I change the tooltip values to be absolute values?

Question

I am creating a population pyramid in highcharter and the way I have got it to display as a pyramid is to change the value for males to be a negative value.

I have successfully changed the labels on the x axis to be absolute values (all positive), however the tooltip is still showing the negative value. Can someone help here please? Code and image below

Thanks

PyramidPlot2 <- highchart() %>%
  hc_add_series(PopEDBinded, type = "bar", hcaes(x = c(PyramidLevels,PyramidLevels), y = value, group = Gender), color = c("#2f7ed8","#FF0000"), 
                showInLegend = F) %>% 
  hc_plotOptions(bar = list(stacking = "normal")) %>% 
  # format the labels on the x-axis (y-axis per HC)
  hc_yAxis(labels = list(formatter = htmlwidgets::JS( 
    "function() {
        return Math.abs(this.value); /* all labels to absolute values */
    }"
  ))) %>% 
  hc_xAxis(categories = PyramidLevels, reversed = F)%>%hc_title(text = "Males", align = "center", x = -115, y = 20, margin = 0,
           style = list(fontSize = "12px", color = "#FF0000")) %>%
  hc_subtitle(text = "Females", align = "center", y = 20, margin = 0,
              x = 250, style = list(fontSize = "12px", color = "#2f7ed8"))

I am not sure how to add data but here is the output of dput on the dataframe in question:
