Authorize.net plugin {The expiryMonth parameter is required}

Hello,

I have been trying to set up the Authorize.net plugin and whenever I go through the order form I always get an error when it tries to go through
________
Error: 0

The expiryMonth parameter is required
________

Though I enter a valid expiration month.

I have tried

12/25
12/2025
December 25
December 2025

it does ask MM/YY but maybe thought some other way of entering it might help

But all ways of entering it in gives me the same error

I have also tried this on multiple templates, and I get the same error
