That's a issue in your auras named " Temple of Sethraliss - Nox..." and " Waycrest Manor - Devouring...", not a error in the addon. Thus we need at least those auras, though you might get better help by contacting the authors.

Please answer all question from the github issue template and include the auras that are triggering this error
Temple of Sethraliss - Nox...
Waycrest Manor - Devouring...
