I recently updated from a 5 slot ZWO filter wheel to the 7 slot filter wheel.
Unfortunately, I am unable to assign a label for filters #6 and #7, as there are no edit fields displayed to enter themt. It properly detects the FW as a 7 position FW and I am able to select the unnamed filters.
Additionally, these filter positions cannot be changed in the capture tab. It displays the 7 filter position, you can enter the labels for #6 and 7 positions, but they will not save.
