The ERC dialog looks like the one of the nightly builds. Are you aware that they might not be the best idea for beginners? Is it a good idea to use a nightly build version?
And well either there is something wrong with the nightly version you use or there is a problem with your schematic.
For further help you will need to share your exact version info from about->kicad->copy version info (or similar, nightlies might have a different structure for the graphical interface)
