Pro Tools 12.2 HD clip indicators don't work

[djani]

Hi, just to check if anyone have this problem.
When I push all tracks over the top into AUX mix buss the meter doesn't show any clipping. Though if I insert a plugin on mix bus it shows me that input signal is more than 5 db over zero... Output meter in right upper corner is set to show mix bus input - no red there. Prefader metering is on, same thing when meters set to protools classic or linear or any other scale. In preferences settings clip indicator set to hold 3sec as usual. I don't have slightest idea whats going on... Simply no Red !!! I'm on Mac OS X 10.9.5 and 10.10.5 same thing on both systems.
