I’ve just reported this bug by the Unreal Bug Submission form (https://unrealbugsubmissions.epicgames.com/s/?language=en_US&token=ArWm4MY4CmUeDmDHXRGxSi6aE1UpPj72PSQQ), because I’ve not found any logged issue about this problem (Unreal Engine Issues and Bug Tracker (Search Results)).
I hope I will receive a message from Epic Games team, but if someone knows a workaround for this bug please let us know.
