If there are more than 20 blueprints in the Clarity PPM Application, you are unable to edit/change the blueprint value for a Project, Idea or Custom Investment

Steps to Reproduce:

1. Under blueprint admin, generate over 20+ blueprints (it could be any combination of Projects, Ideas or Custom Investments)
2. Go to either the Project, Idea or a Custom Investment grid, and try to update the Blueprint field

Expected Results:  You are able to update the blueprint field

Actual Results: You get the following error: CMN-0009: Attribute 'Blueprint' has invalid Lookup Value '5000002'

Here is the output in app-ca.log:
