I have configured PAFL delay to 150 ms and PFL trim to -18 dB as shown in the attached screenshot.
When I select PAFL on an input channel, I listen to it with the configured -18 dB trim as expected.
When I un-PAFL that channel, thereby listening to Main LR (which was PAFLed prior to PAFLing the input channel), the listening level spikes to 0 dB (no trim) for the 150 ms, that I have set as delay. The same spike appears if nothing was PAFLed prior to the PAFLed input channel. It means that when I un-PAFL the input channel, I will hear it for additional 150 ms with no trm (very loud).
Obviously, the issue disappears if I set the delay to 0 ms.
(the -18 dB and 150 ms are exaggerated to demonstrate the issue)
