Auto fire mode changing to burst / single fire without a button being pressed

I have been playing Battlefield 6 with friends over the weekend and since playing I have been experiencing all automatic weapons I have used will randomly change firing mode without me toggling it via D-pad. Once the fire mode has changed to burst/ single fire it does not revert back to fully auto even after pressing the D-pad. 

In addition to this, bullets are not registering even though it is clearly visible the bullets are making contact with other plays. I understand both my issues have been previously been raised by others, but this makes the game feel broken.
