Hi
A clarification is needed here. tchi1 should be considered a toponymy hierarchy. This hierarchy type allows it to be used in any portal as any other toponymy hierarchy.
rsc65 and rsc92 make a calls to all toponymy hierarchies. However, the issue is that you are not seeing the names of the immobile records. So, the Request Config must define the tchi15 into ddo_map (the ddo chain) to show the names, in the same way than other toponymies use hierarchy25.
The change was done into the ontology:

Update your installation to obtain it.
