LibreCALC: How do I make data label text wrap on graphs STAY enabled?

[KyCube]

When I want a text on a data label to wrap, I:

1. Select the data label.
2. Right click on the label and choose “Format Data Labels…”
3. On the Data Labels tab in the “Text Attributes” section I select “Auto Wrap Text.”

If close the document after saving and then re-open the document, “Auto Wrap Text” is now disabled again. Is there a way to FORCE this to stay enabled?
