Sorry to hear about that. I will do some testing on the remote station feature to find out.
One new option that got introduced in firmware 2.1.7 is the ‘Special-station Auto Refresh’ option, which is turned off by default. In firmware 2.1.6, special stations (including remote and RF stations) are automatically refreshed to make sure the remote stations are in sync with the master controller. Due to several requests, we made this an option that you can choose. You can go to Edit Options -> Advanced, turn that flag on, and see if this makes any difference.
