Steps I took that resulted in the problem:
Created breadboard projects, router parts on schematic view. PCB view shows connections between parts, that are not electrically connected. It also misses connections that are present on other views.
"I2C" header has 4 pins: 3V3 (pin1), GND (pin2), SDA (pin3), SCL (pin4). SDA and SCL are only and directly connected to Wemos pin D1 and D2. You can see that on BB view and schematic view all is completely correct there. On PCB view pin 2 and 3are connected together, to ground and to pin D2.
I think I might have messed something on schematic view
What I expected should have happened instead:
Correct connections on PCB view.
My version of Fritzing and my operating system:
Mac OS X 10.11.6, Fritzing 0.9.3
