I got a pc and a laptop, both using qgc3.2.7. Recently I upgraded my pixhawk2 to px4 ver1.8.1. But when it was connected to pc, some params (e.g. the params in serial tab) are shown in the default group, and with no description content. But when turned to my laptop, the params are listed in the right position, with full description. This should be some problem with meta data, but seems really weird. I've tried to reinstall qgc and to install a latest 3.4.4 version, but still the same. Can anyone help?
