It probably is a program bug since every pin has his own terminal as well. Not sure why it isn’t getting them but a quick fix is pressing “W” or “E” buttons on schematic view when creating the part.
For real, there isn’t an alternative way for the PCB view to auto assign the pins?
Unfortunately, the groove connector doesn’t have 0.1 grid spacing since they are way bigger than that. I think it was done by aesthetic purposes.
After thinking a bit about the grid spacing on breadboard view, I decided to fix everything so the part will fit on the Fritzing grid.
I struggled a lot but managed to find the correct alignment after doing some resize of the connector boxes. The schematic stuff got fixed too after xml editing and also the internal connection were added. Finally, the exported piece as .fzpz file.

I feel soooo good after the final result. This piece was more like a training for mastering Build your own piece after struggling with Fritzing stuff.
