Procedural Foliage Spawner not using all Foliage Type Objects

Currently in the process of making a forest using the Procedural Foliage Spawner.

I have 53 Foliage Type Objects in the Foliage Spawner array. Is this too many to use?
When i use the Foliage Spawner Volume on my map, it only puts in the last 27 Foliage Type Objects onto my map.
All the Foliage Types have identical settings, so that isn’t the issue.

The second part that puzzles me is that as shown on the image below, the Foliage Types used are not evenly distributed, it’s instead heavy on the first few and lighter on the rest as it goes up the array.

Is there a setting i have missed or is this just how it currently works (with it being experimental)?

I think i can do a work around using multiple volumes and less in each Foliage Spawner(array) but we shall see.

Did you ever figure this out?

I think I figured out my issue. I had almost everything set to a higher density, except for the items I was missing. Once I changed the density they showed up.
