I'm building a Tidbit and I've socketed the MCU in order to test what I have so far. I am new to this and frankly I don't trust my soldering! When I short each switch's pads I get the output on the blue paper. Should I be getting multiple keystrokes like this? I was expecting single keystrokes at this point.
The rotary encoder is working for volume so I'm super happy about that at least
The kit is really nice and I'm going to use it to speed up my photo processing workflow.

Solution
Thank you again for looking at this. After a very drawn out investigation I realised that all my cheap MCUs all have a fault with pins GP26-29 being connected to earth (I am not alone it seems https://www.reddit.com/r/olkb/comments/1fm1o32/rp2040_cant_use_gp2628/). Coincidentally, these are the column pins on the Tidbit. This problem never showed up on my first project because it didn't use those pins. On the plus side, I now know more about keyboard circuits than I ever wanted to! I can make work by removing the header pins on the bad GPIOs and wiring the columns to unused pins. It will not be pretty but it will work.
It's academic now, but to answer your questions: The socket is Mill-Max 115-47-624-41-001000 and pins 3128-1-00-15-00-00-08-0. The LEDs work perfectly, which I am very pleased with because they are the first thing I ever surface-mounted
Thanks again for taking the time to help.
