Issues with RBG and CMYK

To whoever that can help out, 

I'm having issues with colors on Illustrator. It could be something to do with copy-pasting assets from other ai files with CMYK color (I use stock assets in my work) into my RGB work file that's messing things up. 

Even though my document is in RGB mode, the appearances panel refuses to show RBG values, and instead only shows CMYK values even though the color selected is clearly RBG (tried to open previous works that are RBG files and this issue is still present).

The appearance panel tells me that the color selected is "out of web colors" even though it's clearly not (the colors panel shows the pantone code with RGB just fine). I've attached some screenshots whereby the torquise green is not showing up in it's RBG values, with illustrator giving me an option to convert to RGB.

I've reinstalled AI (newest version as of time of writing) but the issue is still there, and I can't seem to figure how to resolve this after much fiddling 😞

Any help on this would be greatly appreciated!
