Description:
========
If there are 3 Global Variables (GV) with the name "port" in different folders and they have different values, then the value is substituted by just one substitution variable.

Solution:

When the "Service" field is checked at the Global Variables (GV) level (Designer), all GVs are promoted as Substitute Variables. The Substitute Variables do not support grouping or folder structure.

If two GVs have the same name but are located in two different folder structures (like - /folder1/name1 and folder2/name1), AMX drops the folder name and picks only name1 and uses it for all GVs that are in different folder structures with the same name.

There are two workarounds for this issue:
