Data extraction bug?

Has anyone else experienced this with data extraction?

I extract coordinates and attributes from blocks.

In step 4, I want to change display names for some properties, see screenshot 1.

But when I hit Enter, my entered display name appears in the "Category" column, not the "Display name" column, see screenshot 2.

And when I continue, the display names are reset to default, my edited names disappear.

Is this a known bug?

As a workaround, I unlock and edit the extracted table.
