You have a few problems. Connector39 to 50 have layer="unknown" in the fpz file which means the connections aren't active in any of the views for those pins (they need to change to breadboard, schematic, pcb as appropriate). Your view box is also over large, but thats not a big issue, but in Inkscape edit->select all then file-> document properties->resize page to content will fix it. In schematic the connections are connecting to the center of the pin because you haven't defined an appropriate terminal in the schematic svg (although they are specified in the fpz). I usually use a rectangle .01 by .01 centered on the end point of the pin as the terminal. PCB looks ok to me (but I don't do much with pcbs either ), you probably should add an outline drawing to the silkscreen layer though. As well the url listed above github .com/troelssiggaard/ESP32-fritzing-module/ has a space between the github and the .com which makes it not work on a cut and paste.
