Dependabot alerting on file which not exists anymore

Hello everyone.
I’ve got an issue.

I’ve setup Dependabot on my repository a long time ago.
Since then my repository folder changed.
Now i’m continuing receiving Dependabot alerts about content of files, which not exists in my repository anymore (in all branches).
Like this one:
But package-lock.json is removed already =>

Is there any way to update or something like this Dependabot source \ settings?

If this is a wrong place to question - please, tell me where i can ask about this issue.
Thank you
