Dear shamaliabhavin,
You can validate higher SIF values once you select B31.1.
In B31.3 you saw same values because user need to mention SIF manually.
Presently, I don't have a copy of B31.3 with me but I remember (with my limited memory) that such condition is cited in B31.3, Appendix D Note 11 or 13. Hope this helps.
