My phal is growing mold on its flower spike

[Autumn Child]

I need advice on the mold growing at the base of the flower stalk and the spike (first picture). When I try to investigate by rubbing my finger on it, it felt sticky like sugar water. I also discovered that the newly opened flowers secretes sugar water/nectar at the base of the flower stalk and the spike (second picture). This nectar cause the mold growth.

My question is:

1) is this normal?

2) is the mold harmful to the plant and people?

3) how do i get rid of it?

Thanks
