Exclude issues or not understanding properly


I’m running Seafile client 7.02 and are trying to set up a rule to exclude syncing of raw photofiles to one of my clients.
I have placed a file named seafile-ignore.txt in the root of the library (locally on the client) with the following content:


I unsynced the library and deleted the files locally (all except the before mentioned exclude-file) and resynced, yet the .ARW files on the server was still being synced.

Have I perhaps misunderstood the exclude-function or is it somehow broken as of late?

Best regards
