Problem: Save for Web & Devices keeps changing my document size

[iamcarpetpython]

Problem:

I have a working image in Photoshop with this as it's Image size:
Image size
Pixel dimension width:1700 height:2200
Document size width:8.5in height:11in Resolution:200

but after I 'Save for Web & Devices', it changes the dimension automatically to this:
Image size
Pixel dimension width:1700 height:2200
Document size width:23.611in height:30.556in Resolution:72

I think the problem is that the resolution is getting set at 72 no matter what. I have not had this problem until yesterday, now it does this with every file that I create. I think some settings got tampered with, and I don't know what it is. Need help.

I could be wrong but I know PS Save for Web & Devices will always save a jpeg at the webs normal setting of 72 dpi.

In the Metadata section of Save for Web you must select
"All Except Camera Info" or "All" to retain PPI.
