OpenRoads Conduits - Feature properties not matching Utilities properties

We are modeling a drainage network in OpenRoads' drainage and utilities tools. When modelling from scratch it seems to work fine, but if we start changing things, the model starts behaving strangely:

- If we add a new section to the catalog, it takes some time for it to appear in the conduits properties

- If we change a conduit's feature definition that has a different type of section (for example from circular to elipse) it doesn't assume the new sections on the "description" field. 

- If we change the feature definition to one with a different material, that change isn't reflected in the 3D model visualisation

Has anyone seen this behaviour?

Using OpenRoads 10.09.00.91
