Dear consumer,
It's so strange that the I2C scanner does not show the RTC internal address but that the internal RTC can be also working.
The only reason I see possible is that the red switches that enable the I2C towards the outside of the equipment are disabled (see image)
Also check the following link as it is a practic example of the RTC usage and also the SD data storage:

I hope I have solved your problem.
