Some members reported that the issue started after updating to the latest firmware, but I think not - my set's MLL rose without applying any updates. The issue seems to be very similar to Panasonic X1/S10/G10/V10/Z1 models MLL rise, which received a fix after the issue was brought to attention. With these sets - MLL rise seems to happen much faster, but I am hoping that a similar fix can be done for them if enough people have and report the issue.
