Tooltip disappears when Legend applied to scatter plot

Hi,

I have a scatter plot showing when a member of our team last spoke to an organisation (to aid regular contact). The plot's tooltip usually shows the date of the last contact (X-axis), interest score (internal metric - Y-axis) and name. However, we have a new classification system (1 to 4) which I am trying to apply as a legend so that we can prioritise any high priority organisations. However, the moment I apply the legend, the name disappears from the Tooltip even though it is still applied in the Build Visualisation pane.

Screenshot of what the plot and tooltip usually looks like here.

After applying legend, this is what it looks like

Any help is appreciated.
