REW help please

Graphs dont look right, I have been back and forth with the help section and cant get a graph to look anything like my previous measurements.
I also get the warning that signal to noise is too low.
I have not changed anything in my system since the last time and wanted to measure before testing some different woofers
Any recommendation of what REW setting I have changed?
Top two graphs are from last session about 3 weeks ago
