LightSwitch is still looking for an entity property that no longer exists in any project file. How and why?

Question

I recently performed an across-the-board rename in my LightSwitch application and development database. (No worries, always backups.) I know that directly editing the .lsml files (Client.lsml, Common.lsml, Server.lsml) isn't supported - you must be careful.
That said I've been able to use find and replace within these files with great success for simple refactoring ... until now.
I renamed "WcsNum" on my Job entity to "JobNum".
I have a data grid whose entities include a relationship to "Job" and display a couple of Job's properties, all very typical. Now whenever I open the screen with the data grid and it's populated with one or more entities that have a reference to a
job, I receive this:
The property 'WcsNum' does not exist on type 'LightSwitchApplication.Implementation.Job'. Make sure to only use property names that are defined by the type.
The spooky thing is, the text WcsNum no longer exists anywhere in my entire project. I've used Agent Ransack to search my entire project directory including the main LightSwitch project, my WCF RIA Services project, and any related files.
I've even exported my database schema (and data) to scripts and searched those for it -- nothing.
I've tried "Clean Solution", as well as manually deleting every obj, bin, and GeneratedArtifacts directory in both projects. There are no remaining occurrences of this reference, I don't know where it's getting it from.
I also tried deleting the settings from %UserProfile%\Documents\Microsoft\LightSwitch\Settings, which I regularly clear anyway to discard manual column sizes.
As I'm typing this I'm searching the contents of every file on my entire computer for "WcsNum", in case there's some other local cache that needs cleared. Feasible with a solid state drive.
If I can't find it this way, it must be stored differently, or within a binary format that Agent Ransack doesn't recognize as ANSI/Unicode.

For the first question, in Solution Explorer, you'll find a folder under the LightSwitch project called "Data Sources". But here's the bit you might be missing. You have to switch to back to
Logical View, if for some reason you've switched to File View. You won't see the data sources if you're in
File View. And seeing as you've got Luminous Tools installed, if you have made the toolbar visible, then you have a button to do it all for you "Show Data Sources". Then you simply right-click the data source that is your RIA
Service, then select Update Data Source. I hope that makes it a bit clearer for you?
As for not seeing a Rebuild Project command, you might be looking in the actual LightSwitch menu. What I've done is only put commands in there that directly relate to LightSwitch. Any others will appear in one of two groups in the context menu underneath
the LightSwitch menu. Rebuild Solution, Rebuild Project, & Cancel Build, should all be together. If you still can't find it, let me know. Any images of what you're seeing on the screen would be very helpful for me to know what to advise you.
