I did try to add an analog for left and right views but have since deleted.
can I fix this some how ?
should I delete game and re- download?
Did that too at some point. The most radical thing to do is to rename your existing Settings folder and remap everything, no need to delete the rest of the game.
Before doing that, double check that you've
saved the deleting of said setting. Then map it to the keyboard. If it's mapped correctly, you can try the Fix Key button or Clear the key and remap it.
Also, as FLS said, rebooting your PC may help. Adding to that, in Windows 10 pressing the Shift key while clicking shutdown and then starting normally will reset all stuck or corrupted settings making it a good old fashioned clean start.
