Multicast page not displaying Select Ip's for Unicast Sync

[patdelaney]

Please answer the following:
FPP Version and Hardware:
Example: FPP 8.x master on Kulp k4

Describe the bug and Steps to reproduce:
I have a K4 on network (192.168.50.47) and a Pixelstick running V4 firmware with SD card on a differnt network that is routable. (192.168.1.148).
I have added the 192.168.1.148 to the Advanced Settings UI, Multisync Unicast Discovery IP section for that FPP can find it.

and it does after restart of fppd

Except it is not displaying the Unicast checkbox

**If I log into a different Pi on the same network as the Pixelstick, it adds the checkbox

Expected behavior:
I would expect that the checkbox would have been there and it wasn't.

Additional context:
Add any other context about the problem here.

Are you sure your K4 has the "send Multisync packets" enabled. Your screen shot lists it as player and not player w/multisync. That checkmark to enable unicast is only available when your viewing instance is set to 'send multisync packets'.
