GlobalSection ExtensibilityGlobals is repeated in .sln file

Question

I checked almost all questions w.r.t this on stack overflow, but didn't find appropriate answer.

In my project solution file I can see a repeated entry for GlobalSection with SolutionGuid, as follows:

Global
    GlobalSection(SolutionProperties) = preSolution
        HideSolutionNode = FALSE
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(SubversionScc) = preSolution
        Svn-Managed = True
        Manager = AnkhSVN2019 - Subversion Support for Visual Studio
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
    GlobalSection(ExtensibilityGlobals) = postSolution
        SolutionGuid = {E3949C94-3551-44F7-BE8B-1FFE4A668402}
    EndGlobalSection
EndGlobal

Every time when I open solution in VS2019 creates a new entry of GlobalSection. This should not happen usually a .sln file should have only one section for SolutionGuid. Due to this modification in .sln file, source control detects this as a change and we have to commit or revert it every time.

As you can see GlobalSection for SolutionGuid entry is repeated 7 times with the same GUID. why? How to fix this or this is a bug?
