You don't need the same resolution in multiple places. Just keep one of them. The first detailed resolution has the highest precedence. Also, check the TV resolutions and HDMI support data blocks and make sure to delete 3840x2160 @ 30 Hz if it exists.

Windows lists refresh rates as whole numbers, so anything between [29.5, 30.5) Hz will be listed as 30 Hz.

Refresh rates are not guaranteed to be exact because of hardware clock variance. The difference between 29.97003 and 29.96954 is 0.00049 Hz, which is very close, so it looks like it's working to me. It might be possible to nudge the refresh rate closer by changing the timing parameters, but making fine adjustments like that is difficult.
