Asset's memory usage goes up even if I'm not using it at all. It looks like my LG TV is responsible!

My LG TV is listed as a Control Point as below
Linux/4.4.3-208 UPnP/1.0 LGE WebOS TV LGE_DLNA_SDK/1.6.0/04.71.00 DLNADOC/1.50

So I've pasted this to the Blocked control points in the Overrides section exactly as above.
But the logging from my TV continues. Looking at logs-upnp I can see a lot of logging. Sample below.
[16:19:52]

Have I missed some syntax in the blocked definition?

Thanks
