These two buttons here: https://i.imgur.com/MFpDS7C.png
They do not send any input when held, meaning if you bind something like say, Block to them, any blocking will only occur for a brief moment after you've released the button.
As far as I can tell, all my other buttons are working fine. It's just these two buttons that are acting up. I've tested the Dual Stick device on my computer to confirm it's not a hardware defect. I do have my Dual Stick set to Mode 1 properly.
I am on 4.1 April 27 and I have already reset my es_input.cfg after updating.
