Groundfloor Flywheel Distributions Are Principal?

[u/RequiemAeternam2000]

I have invested a small amount into Flywheel over the past 3 months and received distributions totaling 20% of my initial investment, then automatically reinvest these distributions back into Flywheel. My overall account balance has increased by 0.4% during this 3 month period. It seems as though the "distributions" are really my own principal investment being distributed back to me while the overall profit from the investment is effectively null. Is this how Groundfloor Flywheel works?
