I think the problem here is that the order of application of modifier meshes vs. layer range modifiers is not well specified. You better not overlap the two.

Neither the modifier mesh nor the layer range modifier specify a bottom layer in the bottom 1mm of the model. So it isn't a simple order issue. Also, since the modifiers are modifying different settings, the order shouldn't matter. One modifies bottom layers, the other modifies infill %.
I've also flipped the layer modifier to remove the bottom layers in the first 1mm of the model and set bottom layers to 1 for the entire model and the results are the same.
Likewise, I've set the entire model to 0 bottom layers and then created two layer height ranges. Range 1 from 0-1mm with bottom layers set to 0. Range 2 from 1-210mm where bottom layers are set to 1. Same result.
If I disable bottom layers everywhere, then it works correctly. But if there is a bottom layer anywhere in the model (at least in the overall settings or layer range modifiers) the bottom layer will appear.

It seems to work now in PrusaSlicer 2.4.0-alpha1. The order of application of modifiers is:

1. Layer range modifier
2. Modifier volumes in the order they are listed at the side panel, last wins.
