Setting test point size

In X6, I select the Text tool, then in the docker or on the tool ribbon I set the point size to, say, 12 points.

But, with the Text tool still active, when I click to deposit artistic text, the point size changes to 24 and the text is deposited in that size.

Next time I select the Text tool, the point size shows as 12. But when I click to deposit artistic text, the point size changes to 24 and the text is deposited in that size.

How can I arrange for all artistic text I deposit to have a certain point size I choose.

Thanks.
