@VectorStyler At the time I was just playing with the functionality and I posted it as question as it did not even occur to me it was unexpected behaviour. As such, I did not keep the original shape that I worked with to create my variation. I must have hit some extreme or applied an effect twice perhaps, as you can see in the shape, the petals are sort of heart shaped (indents are alternating). I do not even have a clue how to replicate the base shape. I did play a bit with the functions option too (S-Curve, Hanning, Sphere, Pinch). Not sure if this is worth pursuing. I now know that my nodes were not cusp, and I know how to correct this issue if it occurs.
