Parts of support starts "mid air" a few layers in to print?

[janjoh 0]

So, I am running Cura 4.4.1/Win64 and I have noticed that on several models as of late parts of the support seem to start "mid air" usually around layer 4.  This, of course, generally does not work very well. And I can not figure out if I have messed with a setting, or if this is actually a bug. Any help appreciated. On the enclosed file, that a look at layer 4 and 11 on the "outer" support.

Try with support placement set to touching build plate  and support pattern as grid

That (changing to grid) seem to have fixed it... Any idea as to why?
