If your club upgrade rate includes the $100, it will be called "$100 Property Credit & Club Upgrade Rate". I cannot recall if there was a version without the $100 credit but I seem to recall that there was one to be used for one-night bookings which didn't qualify for the credit. If your rate doesn't mention it, call in to 1-800-542-8680 (this is not the normal Marriott number) and ask them to fix it, and mention rate Z38 if they're having trouble.

One final thing to note is that the first rate in your screenshot is the rate pertaining to your SPG Luxury card and the second one is the rate for your RC card. Each rate specifies that you must pay with the specified card so keep that in mind, although who knows if the property will actually enforce it.
