In Xfce display will not set or hold the proper resolution

Hello! I’m using Xfce, it’s a fresh install and has been updated. When I try to set the resolution of my second monitor from the Display GUI, the resolution does not change but I am prompted to keep the new configuration. When accept, close and then reopen the Display GUI, it’s reset to its native resolution. I was able to set it to the desired resolution with xrandr, however windows do not seem to scale properly within it. The monitor is a CRT and I’m trying to set it to 800x600 as it’s sharper there than at it’s native res. I know it works and I know windows are able to scale properly within it at that resolution as it worked on my previous install of vanilla arch using Xfce as the DE.
