A320neo transponder won't hold my squawk code

My A320neo is acting strange. The transponder won’t hold my squawk frequency and my radio is not displaying any frequencies.

I cannot manually change these items and the AI cannot program the squawk code either.

This is recent, i.e on or before 20th December 2020

Is this a general issue or just a problem I am having?

It’s called a “squawk code”, because the code is broadcast steadily, it is like a bird squawking.
The code will enter itself when you get ATC clearance.
The radios are in the FCDU, the nav rad pushbutton.
You enter them in from the FCDU keypad.
If you already knew all this and it’s no help, have you tried turning all your assists off and see if you still have the issue.

Not just the squak code, I can’t set the nav frequencies or com frequencies either but thanks for the suggestion

Seems to be the one aircraft, have I pressed a button or what, I don’t know just thought I would ask the experts and save flying time.

On my transponder, I have a code in, but can’t change it when ATC tells me to enter a code, it reverts back to the original one.
