Saving Jpegs in sRGB

Noticed some color issues on my web site looking at images saved as jpegs in PS CS5. I swear I had the profile sRGB box checked in the save box. I redid it just to be sure. They were in an unknown color space so the browser didn't have much guidance though color aware.
For some reason the jpegs after processing are not stored as SRGB color space but uncalibrated. Only way now to accomplish this is to assign the profile from the edit menu. I never has to do that before. I must have balled up some default setting, but I can't figure it out. :confused::confused: Any help much appreciated.
