[Ifeffit] EXAFS fitting - Reff command not recognized

Hi all, I'm having an issue where I want to use a * reff (also tried a*reff, a * Reff, a*Reff) as the expression for delta R, but instead of recognizing the command Reff, Larix now considers this a parameter it should fit, whereas in the past it would just use the value for Reff contained in the path in question. Is anyone else experiencing this issue as well and if so, how can I fix this?
