Hey Sajid, Thank you for taking the time to report the issues. I’ll fix them in the coming updates
As for the content folder structure, I prefer placing it in root as it is easier to convey the message of directly copying it to the content without any confusion of an additional step of creating a sub folder (if individual folders are to be copied).
You can always move them to a subfolder if you like, but you should let Unreal Editor do it for you (instead of directly copying it your subfolder). So place them all in the content’s root folder. Then come back to UnrealEd, and move them to your subfolder from the content browser so it can create proper redirectors and not break anything
