REW stops measuring at 200hz, not sure why

[whazzup]

Hi, newbie user here. Still trying to complete my 1st complete measurement in REW (5.20 beta 53). Ran into an issue where for some reason REW stops measuring at 200hz.

I'm using Umik-1, and a USB DAC > Amplifier > 2 speakers + 1 sub. Windows 10 OS.
Oh, and if it matters, I'm using this system on my desk in front of me (~50cm away), in a roughly 3x3m room.

I followed the umik + REW setup guide and completed the 75db part, but otherwise, it's a fresh installation with the default settings.

Thanks in advance!

Ah....please ignore, for I had not noticed that the frequency range was only set to 200hz in the measurement dialog window. Not sure why that's the case, but it works now.
