Multiworld Console Command Block Output

Hello! So I have a server and it has Multiverse installed. I have a total of 4 worlds, world, world_nether, world_the_end and testing. In the testing world, I have made a command block clock controlling a sign using /setblock. Because it's a clock, whenever those chunks are loaded, the console gets spammed with "[Server] INFO [@: Block placed]" even when all 4 worlds have the gamerule commandBlockOutput set to false. Is there any method of disabling commandBlockOutput to the server console? I am fine with installing another plugin to stop this too so all methods possible through Multicraft or FTP are possible. Thanks!
