The configuration mixing between the first two $0^{+}$ states in ${}^{98}\mathrm{Sr},$ which have very different deformation, has been reanalyzed by introducing the term involving the intrinsic $E2\mathrm{}$ matrix element between them in a two-state-mixing model calculation. A mixing strength of $\approx 2.6\%$ was determined using the known $E0\mathrm{}$ strength and the intrinsic $E2\mathrm{}$ matrix elements for those two $0^{+}$ states. This mixing strength is nearly a factor of 4 weaker than that of the early analysis. Comparison is made to a similar case of configuration mixing in ${}^{100}\mathrm{Zr}.$
