Speed limit enjoyment, alerting below 20 mph.

[BizarreBleak]

I have had my Niro 4 HEV 24 (lease) for one week. Speeds beyond 20 mph are OK; the vehicle indicates that the speed is appropriate. However, below 20 mph, it emits incessant beeping. I have chosen the information alone on the speed advisory menu, nevertheless it defaults to emitting beeps and announcing the speed regardless of my attempts; I am unable to "save" the adjustments.
At 30 mph, it is OK; but, at 33 mph, the indicator goes red without emitting a beep. This pattern persists at 40 mph, 50 mph, and so forth. Any suggestions?

One should not get any speed alerts while going below 20 mph. Neither the cruise control nor the speed limiters may be configured to a setting below 20 mph.
Is the device designed to emit a beep at all speeds down to 0 mph, or is there a specific speed threshold at which the chirping ceases?

Does that indicate "Accelerate"?

Two weeks after Stonic ownership, there is a nearby supermarket where the vehicle detects a 10mph sign and emits three beeps if the speed limit is exceeded, subsequently allowing further acceleration without further alerts.

It seems to emit a beep alone while transitioning between 20 and 30 indicators. While travelling, you see a 20mph speed limit sign. The vehicle will emit a beep if you are travelling at 23, among other speeds. However, it will cease operation if encountering a 30 mph sign. Travelling at 33 mph is acceptable in a 30 mph zone, but there are only 20 mph signs present. Although the detection for schools is on, there are no indications of children crossing on my heads-up display or the vehicle console when it emits a beep. The problem is that it does not let me to retain "for info only" as an option. I will capture some photographs and return to everyone shortly.

It likely perceives 23 as too rapid.
At what speed does it emit a beep in a 30 zone?

[BizarreBleak]

It only provides information in 20 mph zones; for 30 mph, 40 mph, and other limits, it only indicates the speeds without more details.
The one issue is that I have activated silent mode; for instance, when it detects proximity to a school, it engages electric vehicle mode. I will get photographs.
