opencover not calculating code coverage for actual referenced dll/assembly

Please provide the following information when submitting an issue.

Where appropriate replace the [ ] with a [X]

My Framework

[X] .NET 4.6.1

My Environment

[X] Windows 10

I have already...

[X] repeated the problem using the latest stable release of OpenCover.
[X] reviewed the usage guide and usage document.
[X] have looked at the opencover output xml file in an attempt to resolve the issue.
[X] reviewed the current issues to check that the issue isn't already known.

My issue is related to (check only those which apply):

no coverage being recorded

Expected Behavior

opencover should calculate code coverage for actual referenced dll/assembly (Project Reference .csproj)

Actual Behavior

opencover not calculating code coverage for actual referenced dll/assembly rather showing code coverage for test.dll

Steps to reproduce the problem:

[X] reviewed the usage guide and usage document again because we know you probably didn't do it the first time.
[X] sample code or link to repository/gist is available (support is much faster this way)

C:\POC\CodeCoverage\OpenCover.4.7.922\tools\OpenCover.Console.exe -register:user -mergebyhash -target:"C:\POC\CodeCoverage\xunit.runner.console.2.3.1\tools\net452\xunit.console.exe" -targetargs:"C:\POC\CodeCoverage.POC\CodeCoverage.POC.Test\bin\Debug\CodeCoverage.POC.Test.dll C:\POC\CodeCoverage.POC\CodeCoverage.POC.OtherTest\bin\Debug\CodeCoverage.POC.OtherTest.dll" -output:"C:\POC\CodeCoverage\CoverageXML\CoverageReport.xml" -filter:"+[] -[xunit.]"

C:\POC\CodeCoverage\ReportGenerator.4.4.7\tools\net47\ReportGenerator.exe "-reports:C:\POC\CodeCoverage\CoverageXML\CoverageReport.xml" "-targetdir:C:\POC\CodeCoverage\Report"

CoverageReport.xml says opencover skipped due to missing pdb for dll for which I want code coverage to be calculated.

 <Module skippedDueTo="MissingPdb" hash="DC-08-91-78-6F-25-E3-39-29-79-8E-45-50-26-43-1D-42-34-F0-04">

    </Module>

Why it is finding Actual.dll pdb files at C:\Users\xxxx.xxxx\AppData\Local\Temp ?? I am executing above commands from root folder of Actual.dll
