Dynamic dropdown in Version 7.5.1

Hi,
I have two different installation of SuiteCRM Version 7.5.1

Installation a)
In Studio, case module, there is “status” field. It is a Dynamic dropdown showing just these data:

Data Type: Dynamic DropDown
Field Name: status
Display Label:
System Label:
Help Text:
Comment Text:
Default Value:
Max Size:
Required Field:
Audit:
Inline Edit:
Importable:
Information
Duplicate Merge:
Information

but I cannot see the Drop Down List and Parent DropDown
1 Question: How to fix it ?

Installation b)
I see:

Data Type: Dynamic DropDown
Field Name: status
Display Label:
System Label:
Help Text:
Comment Text:
Drop Down List:
Parent DropDown:
Mass Update:
Required Field:
Audit:
Inline Edit:
Importable:
Information
Duplicate Merge:

So, better than installation a), but
2 Question: How Can I see and modify the relationship between the entries of the Drop Down List of “State” and “Status” ??

Thanks in advance
Regards
Walter
