Hello, I am having an issue with reading variables to be written on output file from a .SFI file. It seems when the file is loaded, it is losing variables. Each time I return to the screen for 'Definitions for exporting ASCII file', and read the same file from model library variables get suppressed. It seems to be random as I tried again and am back up to more variables. It seems to change every time I open the screen and load the file. Does anyone have any insight to this behavior? Thank you. I am running PVsyst version 6.63
