Basis Set Phase Issue

Hi,

I’ve been creating a .json file for a 3T PRESS basis set and some spin systems and my basis set looks like it has a first order phase across it. I have used the object start times and durations from my sequence object to get my delays so I don’t think they’re wrong? Has anyone else experienced this and know what I’m probably doing wrong, and if it will then cause an issue later down the line in fitting?

Thank you,
Daniel
