Why this differs from similar rows?
Model BM3F: global inversion includes Fiquet et al. [2000] static data, excludes Saxena et al. [1999]; text notes BM3F gives higher K0S, lower K'0S than BM3S (sibling row).

Evidence from the paper
Table 4. EoS Parameters for Solid Phases: Perovskite, Model BM3F, V, Å3 162.35, K0S, GPa 257.0(9), K'0S 3.88(4); 'BM3F yields a higher value for K0S and, moreover and not surprisingly, a much lower value for K'0S = 3.88'
