Weird ~117Hz X Resonance and Belt Tension Graph

I have a Vcore 3.1 500mm that is sitting on the floor. I am getting an odd peak in the X-direction at like 117Hz any ideas?

Additionally my belt tension graph looks a bit odd....I think? Still new to reading these. The peaks seem to line up, but there are 3 of them, is this normal?

Thanks for the help!
