Ok, .rar and .ace shouldn't be there. Those settings refer to zip files only. What you are doing by putting .rar in there is telling Opus that files with a .rar suffix are actually zip files, when they aren't.
Take them out of there, and see [Make RAR, 7z, ISO, etc. files open in Opus on double-click) for info on how to set up rar files properly in Opus.
