Both of my Spark Pro's no longer showed up in my Input Settings. I haven't done anything different to last time I used them with the same session. Then I switch to a 4K session and they came back. I went back to 1080p session and they re appeared.

Anyone know whats going on?

Set Up:
TC1 (Build 4K-170428C, not sure what software version I have, it's never been updated)
Spark Pro
Panasonic 4K HC-X1
TP Link TL SG1016PE
