Is this a bug in Solidworks? Global variables in a Solidworks Assembly model linked to an external text file get changed to the text file linked to a part model of that assembly model with a Pack and Go.

Global variables in a SolidWorks Assembly model linked to an external text file get changed to the text file linked to a part model of that assembly model with a Pack and Go in SolidWorks 2019. Does this still occur in SolidWorks 2020? In SolidWorks 2018, I could do the Pack and Go twice and SolidWorks would again switch file linked file back to the correct linked text file, but now in 2019 a double Pack and Go retains the incorrect linked text file from the linked text file to a .prt in the assembly.
