I am using version 7.7.00 Icon Editor with a S6000 MKII running version 6,50 (DSP + FRAME and Ethernet version 8.10 . I have no gain reduction metering on the De-esser and the Brickwall limiter, but the effect appears to be working.
We confirm the issue with meters on TC Icon version 7.7.00. Please load version 7.5 instead. This will be fixed in the next version.
Note: version 7.7 is not required for S6000 MKII version 6.50 - this version is necessary for other products such as the DB6.
