From support:
Unfortunately, the details that populates under the open with details will stay there. We do not have any options to filter/sort or even remove them permanently.
Since the sharing profile holds the settings for that. We have already tested on our end to disable the Sharing features between Windows and Mac to check if that will make the list be clean. However, it will stay that way while we are running Parallels Desktop.
Please email us back regarding the outcome of the suggested steps/article above if it did help us on solving the concern.
