Anyone else's vapcell s4+ v2 charges a 4th "'ghost"" battery?

Got this vapcell s4+ v2 from wurkkos a little over a year ago, and for a while (a few months after i get the charger) ive been having this issue. Whenever theres 3 cells being charged, sometimes a 4th battery appears on the display, at around 4.3v

Ive attached an image here so y’all can see what i mean
