Image Adjustment values permanently stuck for all .h264 files

[lexlynx]

I have just noticed recently that every time I create a project with a .h264 file, it automatically adds about +10 blue. The interesting thing is that's the value I had been using with a .h264 video I was encoding around the time it became "stuck." Image Adjustment does not indicate the value shift, and moving the slider down to -10 seems to negate the effect, although I'm not sure if that's the exact amount or that any hidden adjustment is completely negated. I had realized that all my encodes since then had been encoded with these hidden added blue settings applied. I uninstalled and re-installed the program multiple times with the three past versions, deleted everything referencing "shutter encoder" from the registry, and even installed the portable version, and this issue somehow persists. I have also reset/deleted the settings in every way I could find. I really don't want to have to reinstall windows to try and resolve this, but have reached my limit of trying to figure out what what could possibly be causing this.

Any help would be greatly appreciated. The attachment includes the source video next to over the same video loaded into the program.
