Hi Marc,
If possible could you share the full xml file, your filter configuration as well as the steps included in your pipeline (especially the segmentation)?
I think those details could be useful for anybody who wants to give it a try to support you.
I took your details and created a basic filter with the codefinder rule, then ran the translation kit creation pipeline with the segmentation enabled and the default segmentation configuration and this is the result: two segments for the for first tu, one for the second tu.
Is that what you were trying to achieve?
