We resolve the difference in the yield ratio ${\mathrm{S}}_3$ = $\frac{{\mathrm{N}}_{{}_{\mathrm{\Lambda }}^3\mathrm{H}}/{\mathrm{N}}_{\mathrm{\Lambda }}}{{\mathrm{N}}_{{}^3\mathrm{He}}/{\mathrm{N}}_{\mathrm{p}}}$ measured in Au+Au collisions at $\sqrt{{\mathrm{s}}_{\mathrm{NN}}}$ = 200 GeV and in Pb-Pb collisi…
