Support material not printing on 2nd and 3rd layer and skipping every two layers afterwards

Is there any way to stop this!? Basically it prints a support interface on the first layer, skips layers 2 and 3, prints support material 1MM away from the first layer, skips the next two and so on. It's causing prints that needs support material to fail. From what I can tell there is no way to get it to print support material on every layer, that's basically all I want, Cura does this automatically and it works beautifully.

Yes I am using a large nozzle, 1mm+, generally .4 or .5 layer heights been mostly printing with PETG lately, but I can't imagine this not being an issue with PLA. 

The only thing I can think if is to just make the support line width like 3mm or so, so it just dumps enough filament to get it to stick to the previous layer, which in my opinion is a lousy solution, I prefer to make my support lines smaller than the rest of the print so they break easier.

Well this is neat, I just pulled up one of my old profiles for a fine nozzle, .1 layer heights, and it is laying support material once every 10 LAYERS. I can't believe I have never noticed this before, I guess I just haven't used PrusaSlicer for things that need support. I just find this baffling, basically just printing support material in mid air. Is this just a bug with the latest release? I find it hard believe that this was done intentionally, generating support material like this has almost zero chance of succeeding unless you just dump as much material out the nozzle as possible so it actually adheres to the previous layer of support. 

I guess I'll just use Cura for prints that need support, besides if it wasn't skipping layers there are far more and better options for generating support material with Cura anyway.

I did eventually find a solution, completely ditch Prusa Slicer for Super Slicer. Has basically the same interface and features along with a ton more options. It doesn't have this support generation problem, and doesn't have annoying settings enabled by default. Only thing I found so far that I wish it had is the pillar supports from the original Slic3r, but I have just begun using it.
