Upgrade from NC 13->14 Email Notifications don't show the shared folder anymore

I’ve upgraded my nextcloud installation from Version 13 to 14.0.12 and am planning to upgrade to 15.0.8 if all is fine with this upgrade.
I am experiencing a problem after the current upgrade:

In Nextcloud 13 the mail notification of an upload to a shared folder contained the folder name and the filename of the uploaded file.
Now with version 14.0.12 the mail notification only contains the filenames but not the folder name.
Is there a way to change this behaviour? Would the upgrade to version 15.0.8 change the behaviour?
