Here is an updated screenshot of what exactly is happening at the moment.
Really hope someone can help with this. Thank you.

PS. I should add that this is happening for any device - condenser mic, SM58, guitar - on both input channels. I even went as far as to send my mic to Rode support, convinced it was the mic at fault, only to be told the mic was fine which was when I realised it was happening with any device.
