Bug in parental controls in Asus RT-AX1800S router?

I bought a new Asus RT-AX1800S. In the parental controls section, you can configure the times at which a given device has access to the Internet - but it doesn't work. The device has access to the Internet at all times regardless of that setting. Does anyone know a work-around? The bug occurs with the current firmware, but also with the oldest firmware available on their website, which is from October 2024. I have already done the following: check the time or time zone: even an all-day exclusion has no effect restart the router upgrade the firmware reset the router to factory defaults replace
