I have similar issues.
I downloaded all 3 Phase logs and they look strange (for me...).
I seems, that the order of the dates in the File of Phase 2 (Figure 2) is wrong.
I plotted the Time of all 3 Phases (L1 L2 L3) - red the Hours, blue the Minutes.
Y-Axis shows minutes and hours.
Figure1 = L1 -> em_data2_l1.csv
Figure2 = L2 -> em_data2_l2.csv
Figure3 = L3 -> em_data2_l3.csv
