I have this fixed and trying to upload new releases to curseforge, but they seem to be having some issues with new uploads there. In the meantime you can grab latest release with the fix for your version here https://github.com/P3pp3rF1y/SophisticatedCore/packages/1386882/versions

this is fixed in the latest release of core on CF
