Number formatting: Not dividing by thousand in graph

That's strange!

In the picture below I have tried to illustrate the problem more clearly. The numbers in the pivot are formatted to be divided by thousand, and the labels and y-axis are "Linked to source".

Even if I try to use the same custom formatting for the labels as the numbers in the pivot, I only get the same strange formatting as you see in the picture.
