Change in SharedLibrary triggers jobs that are using the ShareLibrary

[AckermannC]

Hello,

we have the scenario, that we are using a Shared Library which is stored in Bitbucket.
This SharedLibrary is used by some jobs.

System Environment:

Jenkins LTS 2.346.1
Bitbucket Push and Pull Request Plugin 2.8.1
Bitbucket Server 7.17.3

Now we have this behaviour:

-we change something in the Shared Library
-and create a Pull Request
This triggers the jobs that are using the Shared Library.

So for example:
The job "JT_Bitbucket_PnP_Repo01" starts it's jenkinsfile with "@Library('SharedLibraryGit') _"

In the log it shows first:

Aug 23, 2022 9:46:00 AM FINE io.jenkins.plugins.bitbucketpushandpullrequest.BitBucketPPRJobProbe
jt_bitbucket_pnp_repo01_pipeline SCM doesnt match remote repo {1} or it was already triggered.

But later in the log it shows:

Aug 23, 2022 9:46:10 AM INFO io.jenkins.plugins.bitbucketpushandpullrequest.BitBucketPPRTrigger scheduleJobTriggering jt_bitbucket_pnp_repo01_pipeline # 20
Aug 23, 2022 9:46:10 AM INFO io.jenkins.plugins.bitbucketpushandpullrequest.observer.BitBucketPPRObservable notifyObservers
Event: BitBucketPPRBuildStarted [context=BitBucketPPREventContext [scmTrigger=hudson.plugins.git.GitSCM@7428ebc9, run=Test_Project/IT_Test_Use_Cases/jt_bitbucket_pnp_repo01_pipeline #20, action=BitBucketPPRPullRequestServerAction, filter=io.jenkins.plugins.bitbucketpushandpullrequest.filter.pullrequest.server.BitBucketPPRPullRequestServerTriggerFilter@7267d554, userRemoteConfig=+refs/heads/:refs/remotes/origin/ => https:///scm/itjenksl/sharedlibrary.git (origin), url=https:///scm/itjenksl/sharedlibrary.git, trigger=io.jenkins.plugins.bitbucketpushandpullrequest.BitBucketPPRTrigger@24aa7e81], handler=null] for observer io.jenkins.plugins.bitbucketpushandpullrequest.observer.BitBucketPPRPullRequestServerObserver@2918c62

In the Job it behaves like this:

It doesn't build the SharedLibrary then in that job, but it just runs the normal Jenkinsfile from the Job

Bitbucket variables are:

Can you please suggest how we can avoid this?
