Hello Alex,
What I see in your description is that the filter is based on Suborder / Relation, while the prefill is based on SuborderĀ / RelationContactPerson. These are two different properties in your data-item.
This way the prefill isn’t equal to the filter. This is where the issue lies.
Regarding Rit you filter on a specific ID, while prefilling based on theĀ OrderLine item on the left. There could be a mismatch there.
I hope this helps you to resolve the issue.
