Sounds like the job's targets weren't of the same "type" as the checks in that Standard.
An easy way to see is to EDIT the job and try to choose a single asset which you think should be included by navigating to the asset folder where that asset resides. See the asset?
Yes = it's something else
No = see below
Check Target Type: Manage-Standards, click on any check in that standard, "Target Type" tab. Look at what's in there and compare to what you have in:
Check assets: Manage-Assets, click on any asset you think should be included, "Asset Type Properties" tab.
If the target info doesn't match the asset info, you'll see this sort of message.
