Kid Control Webfig setup

I am trying to configure Kid Control on my HAP AC lite using the web interface; the router is supplied by my ISP as such I only have access to the webfig via browser.

Router is running version 6.43.1 of routerOS

I can configure the Kid Control such that a device is allowed access to the internet during the time periods configured; what I cant do is get the correct syntax for the “Time for Rate Limited” field
So the only notation the field accepts seems to be the same as the time period for the day of the week when access is allowed; i.e 09:00:00-15:00:00; however when running a speedtest while winthin the time window I dont see a reduction in speed that I would expect if the device was rate limited.

My aim is for the rule to allow internet access between 0800 and 2100 mon-fri; and Sat/Sun access will be all day
Also mon-fri the rule should apply a rate limit of 2Mbps between the time of 0900 and 1730

The first bit I can get, its the second bit; I have tried using 0d09:00:00-0d17:30:00; then 1d09:00:00-1d17:30:00 in a new box, this doesnt work and an invalid format message is displayed; adding a colon between the day and time doesnt works and any time > 24:00:00 is also rejected.

Sadly all the online help is predicated on using the console which while I understand all that format I cant access the console.
