The 2022 file in your database having an incorrect current is likely due to how PVsyst interprets unspecified parameters.If a manufacturer provides a datasheet but leaves the Maximum Input Current blank or ambiguous, PVsyst might calculate it using a default formula: I_{max} = Pnom,DC / Vmin,Pnom If the manufacturer's datasheet and the PVsyst-calculated value don't align, you get the weird capping losses clipping you are seeing.
