Y Axis Values in Driver Editor is missing, how to get the values back

When I open a driver editor, the values of the Y-axis are not displayed -Values of X are displayed - Can someone help?

Welcome :tada: ,
AFAIK drivers are added separately for the axis (?) and not for the whole location (like in keyframes). So you have to add one additionally for the Y-axis.

Both keyframes values (X and Y) should be displayed in the sidebar, hit ā€œnā€
