Commented Unassigned: Issue while using NuGet Transform in Config [3360]

I have two packages for my solution where Package 2 is dependent on Package 1. Package 1 contains the configuration file & it is updated with a tag when Package 2 is installed. Now, when I remove package 2 keeping Package 1 intact, it strangely removes one Attribute from one particular tag. Please help me solve this issue.

Following are the screenshots:
