it also has a check mark next to it but both of them are grayed out

It will remain grayed out until the waterfall is generated.

Click the 'Generate Waterfall' button in the bottom right hand corner of the Waterfall page.

Each measurement has to have the waterfall generated.

it shows -180.db

That's the level at the cursor position. It's not important if the cursor is located at a position outside the measurements bandwidth.

Why do you have the vertical scale of the waterfall from -8to 48dB? The signal level will be around 75dB, which is above the level you have set.

Does the frequency response and impulse response look OK?

Let's see them both.

Huh, everything looks fine there.

You're one version back on Java. You might try and update that to the latest version. Just go to the Windows Control panel and open the Java console and update it.

You might also try to select the REW Settings pull-down and select Delete Settings and Shutdown. Then restart REW and try it. (you'll have to rebrowse to your cal files).

OK good. At least it seems to be working now. I have no explanation for the problem....
