Subtype resolution is not finding subtype when defined in another pkg file in another library

[Tcenova]

/python3.11/site-packages/pyVHDLModel/init.py", line 845, in _LinkItems subtype = package._namespace.FindSubtype(element._subtype) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/python3.11/site-packages/pyVHDLModel/Namespace.py", line 116, in FindSubtype raise KeyError(f"Subtype '{subtypeSymbol._name._identifier}' not found in '{self._name}'.") KeyError: "Subtype 'Subtype_Name' not found in 'pkg_file1'."

Subtype_Name is used in pkg_file1 but is defined in pkg_file2. I am still working through on how it searches for the subtype and why _parentNamespace might be None. Any suggestions on if this is expected to work? Or if not any thoughts on how it could work/be implemented?
