[SasView Users] Bug in the version 4.1.2

Dear Development team, I am a postdoc researcher at Swinburne University of Technology in Australi a. I am analysing my data and I am facing one issue from a very time. Guinier-Porod model works well in Q range 1 Guinier-Porod model works well in Q range 2 However, when I customize a model Guinier-Porod + Guinier-Porod, model does not fit at all. Can you please urgently respond to this email and advise on how do I fix th e issue? FYI – I have attached the log file. Same issue was found in earlier versions too – I have been trying every v ersion and no help. Thanks, Rohan Sent from Mail for Windows 10
