Cross project customization: verification issue

Dear All,

I'm using cross project customization feature to allign several projects to same template.

In verification report now I read following difference between template and project, but I don't know what does it mean and why it appear, considering I've not changed anything in this project entities.

1. Project Entities 

2.1. Test  

2.1.1. System Fields

2.1.1.1.  'TS_SERVICE_TEST_MODE' Settings

Name: Edit Style

Before Propagation: ListCombo

After Propagation: TreeCombo

2.1.1.2.  'TS_TESTING_TOOL' Settings

Name: Edit Style

Before Propagation: ListCombo

After Propagation: TreeCombo

2.1.1.3.  'TS_WORKING_MODE' Settings

Name: Edit Style

Before Propagation: ListCombo

After Propagation: TreeCombo

 

Any idea?

Thanks in advance

AM
