Custom Resolution Utility (CRU)

[Mairsile]

I'm having an odd issue I'm hoping for some assistance with.

When I only run 2 of my 3 monitors, I have all of the appropriate resolution options.
But as soon as I turn on a 3rd, I loose the resolution options I want for the 1st and 2nd, and Windows cannot identify them no matter what I do.

Here is what's happening told with images. https://imgur.com/a/QHSirGb

First, I mark monitor 2 as disconnected in the settings - Image 1
Then, because monitor 2 is disconnected, both monitors #1 and #3 display their proper resolution settings as options. Monitor 1 displays 2560 x 1080 and Monitor 2 displays 1080 x 1920 (it's in portrait). - Images 2 and 3
Next, I turn on monitor 2 - Image 4
Now, because of that, Monitor 1 doesn't show anything above 1920 x 1080, which is not correct aspect ratio as it is a 21:0. And monitor 3 doesn't have any 16:9 options. Image 5 and 6

Any ideas out there as to why this happening?
