Both giants orbit more massive but less luminous companions, previously proposed to be mass-gap black holes. Spectral disentangling reveals luminous companions with star-like spectra in both systems. Joint modeling of the spectra, light curves, and spectral energy distributions robustly constrains the masses, temperatures, and radii of both components: the primaries are luminous, cool giants ($T_{\\rm eff,\\,giant} = 3,800\\,\\rm K$ and $4,000\\,\\rm K$, $R_{\\rm giant}= 22.5\\,R_{\\od","authors_text":"Adrian M.
