keepuptodate script losing remote timestamp

Hello,

I'm using the keepuptodate in my script which is being ran by a batch file.
I believe the script is failing where once it completes one upload it loses the timestamp of the files on the remote server.
I notice this happens occasionally with the GUI as well.
Is there a switch I can use to pull the timestamp from the remote server after every upload?

Here is an image of the remote directory, some files have timestamps, some do not.

Please attach a full session log file showing the problem (using the latest version of WinSCP).
