That puts them in series, giving you 6V rather than 3 as we are confident is correct. If you look at the scehmatic, there doesn't appear to be any on-board regulation for the RTC, so you're feeding that pin on the PMIC with 6V, spec appears to be 3V max.
I would tend to agree with xalius that the holder is mis-marked.
I mesured at the conector, it is 2.85v, so it is not feeding with 6v.
