PVsyst monthly accumulations showing months with zero or fewer than 30/31 days

[Operationkilljoy]

I imported a SolarGIS TMY into PVsyst (7.2.11) and noticed that the meteo table shows, under the Interval Beginning column, months have fewer than 30/31 days in brackets. Image attached. It doesn't seem to have affected the numbers but a curious issue, nonetheless.
