Outliner does not report proper uncached lighting count
There is an issue with the scene outliner display of uncached lighting info. The count provided only scores actors with uncached lighting. The problem is that an actor can report 0 for uncached lighting while having any number of components as children with all sorts of uncached lighting problems. These are rather difficult to find. The scene outliner needs to count an actor's components in addition to the parent actor when reporting uncached lighting in the scene outliner.

I actually have this content for my personal projects, and I believe I can help clarify this issue you are experiencing. I took a read over our documentation and you might also find this section of information helpful when explaining why your fences are not generating the indirect lighting cache as you are describing. One of the main points, is to make sure you have a 'LightmassImportanceVolume' as this is needed for Indirect lighting to be calculated.
Indirect Lighting Cache
This information was drawn from our documentation below:
The main thing here is how the samples are placed in the scene itself. "Since 'Lightmass places the lighting samples on top of upward facing surfaces with high density, and everywhere else with low density. The samples are limited to being within the 'LightmassImportanceVolume', and they are only placed on static surfaces."
In this case I decided to reduce the 'Volume Light Sample Placement Scale' to increase the density of the indirect lighting. In the images below you can see the difference between a small scene with a sample placement scale of 1.0 versus a scale of 0.25.
Above is the scale of 1.0 and you can see how scattered these volumes are, and the color they have adopted from the surrounding objects in the scene.
Here I have set the scale to 0.25 and the density of the samples has increased. Now the fences samples are beginning to pick up some color from the fences. The individual pickets of the fences are so narrow that their density is harder to calculate as their faces are not upwards.
This seems to be the reason as well as the objects being dynamic with not available lighting, so it interpolates the lighting from the precomputed samples.
If you have other questions, or think your issue is related to something else please let me know. Also, providing me with some reproducible steps so I can see what you are reporting on my end would be helpful.
