Labels and Total Labels in a stacked column chart

Why are no labels and total labels shown when there is only 1 value in a stacked column??

Here you see I have labels and total labels. Also for the 2 small ones that only have "To Pick".

Now when I only choose status to pick this changes:

Suddenly the labels in the small ones are gone and in the big one there is only the label.

Could be ok with that because label and total label are the same there.

But the 2 small ones losing the labels makes no sense to me!

Yes on the Y-axis you could somehow see how much it could be but of course you want the exact number.

Is there a setting that I am missing or is this just an anoying bug which they have not fixed yet?
