Qwiic Arcade Button (but not specific necessarily)

I have a bunch of these https://www.sparkfun.com/products/retired/15591 (>16) in a project and I’ve been having a number of them lose their saved i2c programmed address.

Initially I thought it was a fluke and I had forgotten to program some of them, but I can verify that 1-2 nights of being powered off they are resetting back to default.

I know it’s probably unlikely to get much support, but I really like these accessories!

The product page mentions needing a mux for multiple on the same bus; is one being used? https://www.sparkfun.com/products/16784

I do have the qwiic mux, but this is happening with only one button on the bus (for testing purposes)
