Tool starting from the bottom on Z-Level finishing

In the file I have posted, I want to utilize the Z-Level finishing strategy with a .031 ball end mill to machine the four deep slots on the feature "Core Pin Cavities". On most of the slots, the tool starts cutting from the top and works its way down, which is what I want. However, on some slots it plunges down into the slot first, before retracting back up and starting to machine from the top again. 

 

This is what the toolpath looks like. First plunges to the bottom, then starts cutting normally at the top edge.

On 3D simulation it looks like this:

Why is it not starting from the top down every single slot? 

 

If this continues to not work properly, I intend to try a different 3D strategy other than Z-Level. What would be a good alternative strategy to machine these?
