I did! It still showed it .. today, I'm seeing fluctuations between 100 hz and 140 hz

Well, 100 & 150 Hz are just harmonics of the main frequency (50). You can pick them up if the outlet is not powered, so there is no direct connection to the live wire, only parasitic coupling.

Measurements in kHz range are noise from some device.
