Data labels are repeated a few times instead of being shown just once

[Vitalite]

Hello!

I have another thread, in which I show the same graph and ask for help on how to replicate the original chart. But while doing so, I have stumbled upon the issue of repeated data labels. Please, see attached excel file. Whenever I add data labels, they are repeated throughout the line. It seems they do so based on the number of X values I have for each line. How so? How can I solve this issue? I would like these data labels to be only on the right side of each line.

Thank you very much!
