Thank you for letting us take a look at this issue for you. After a bit of investigation, I believe I have figured out what happened here.
We are looking at the following part number:
MINI HDMI 19P FEMALE SMT
CNC Tech Part Number: 2001-1-2-21-00-BK
Digikey Part Number: 1175-1704-1-ND
Looking at the datasheet we see the footprint should look like this:
I checked within our KiCad library and found that our footprint associated with that connector is
As you can see this is correct. I checked within the file and doublechecked that it does have the front mask as it should. I also looked into the history of this part has not been changed since its creation in regards to its layout.
What I believe is actually happening is that the wrong footprint is selected. I looked through a couple of the other HDMI connectors and I find this one looks a lot like what you have on your board.
This footprint does have errors as you pointed out. We will be fixing and updating this part. Thank you!
Please take a look and see if this is the case, and as always, if there is anything else we can help with please let us know!
