Modified, Obsolete?

[RailSimulator]

Hey Guys, me again
So Ive been trying to play around with swapping whistle/horn sounds on some of togogs brilliant engines however the content is showing up as "installed from DLS, Obsolete and when trying to change to whistle sound it comes up with Modified, Obsolete. Is there any way to fix this the whistles I am trying to replace them with are only showing up as "Modified".
Regards, Railsimulator09

"Obsolete" simply means that a newer version is installed on your system. To check simply right mouse click on the obsolete asset and select the option List Asset Versions. There will be one most likely labelled as "Installed from DLS" or "Packaged" with no other descriptor and that will be the latest version. It may not have the same name or kuid code sequence as your now obsolete version.

"Modified" means that you have opened and edited the asset. The asset is still "Obsolete" because it has been updated by a newer version so it is shown as "Modified, Obsolete".
