REW acting weird for levels, taking forever, nonsense results...

I've used REW in the past and never had any issues. I loaded it a few nights ago again and it worked perfectly fine. Then I tried it last night and got all the following problems.
.
1) The level calibration does not seem to be reading accurately. What was 83 on my volume knob a few nights ago is now like 60 something and it would likely blow out my speakers to turn it to what it now thinks is 83. Side note, what's a typical adequate level anyway?
.
2) When I run a measurement, it either takes over a minute (I'd estimate) if I have "capture noise floor" checked, where it used to take a few seconds. Perhaps I just didn't have that checked previously, but the major thing is after the sine sweep happens, it sits calculating or doing something for several minutes (where it used to be a few seconds and FR popped out.
.
3) The results if I do wait for several minutes, they look like absolute nonsense, massive spikes near 1 and 2K, perfectly narrow spikes that persist for eons, etc. very odd.
.
Any clues? I'll attach a before and after .... (ignore the 60hz in the before, that was the fridge compressor, ha).. Note also, the "nonsense" file is from 1 foot away from the speaker, whereas the earlier one was at listening position. I've swept these speakers before, they certainly don't have insane spikes around 1-2K.
.
side note, anyone know why I have to put periods for each paragraph separation in this post? Otherwise the separation keeps getting removed.

Problem solved. The I/O in the settings in Console App (Universal Audio Apollo's standalone app) were not set up properly.

Good thinking John..

To correct the issue,
-open UAD Console (separate application),
-click settings in the bottom left corner,
-under the "hardware" tab (top left of the new window that pops up), make sure your specific Apollo is listed there (and remove any other ones probably?)
-click the next tab "I/O matrix"
-be sure your Apollo is turned on and connected of course
-you need to see mic/line 1 and mic/line 2 (or something similar) under inputs
-and if you're using the outputs (I'm not, I'm using a different DA converter for outs), you'll need to see Mon L and Mon R for the first two outputs
-If you don't see this, try just selecting "default" under "mode" near the top left
