(Not the OP)
It happens often to me that slic3r add supports with nothing over them. Sometimes they are "real" support, sometimes they're only on first layer, like in this case:

I'm using Slic3r Version 1.42.0-beta1+win64, on Windows 10 Pro version 1809.

Happens to me all of the time as well. I would have +1 commented an above comment but i see this issue has been dormant for a while. Thanks

The original issue is fixed with 539e80e

When expanding the 1st layer support layer, do it by small steps while
trimming with object to avoid supports to leak through object walls.
