Hello Amaresh and AurochHeather,
Thank you for the clarification, it seems to only happen if you sync to the asset through the editor’s interface instead of perforce itself. I’ve placed a bug report into the database about this issue under the number UE-20789. In the meantime, I don’t have any sort of workaround past suggesting that you use the perforce’s interface to sync to your assets.
Have a nice day!
