Making the Flownumbers invisible

I have a arrangement of 8 parts. I want to name them ‘Acht dansen I’ until ‘Acht dansen VIII’. In the score I have added a separate text frame in the Engrave mode for every part. That works, but…
In the parts the titles are shown as ‘1. Acht dansen I’ until ‘8. Acht dansen VIII’.
How can I get rid of the numbering 1 to 8 in front of the title? It has to do with flows, but I can’t find the right place to cover this problem.

You need to edit the Flow Heading, in Engrave mode:
