Manual recording channel error - "Please select an item in the list"

[vdrover 42]

When performing a manual backup, I get this error in the web app in both Chrome and Safari on Mac: "Please select an item in the list" (see attached). As such, no recording is scheduled and I remain with the scheduling window open.

As you can see, "ABC" is displayed, but Emby doesn't accept that. If I click the dropdown channel selector, there is a checkmark on the "ABC" channel.

If I use Chrome's dev tools to look at the html, the "value" attribute of the channel option is empty (see attached). Manually editing the html with dev tools so the value matches the channel I selected in the dropdown allows the scheduling to complete as expected. 

I am using Emby Server 4.7.6.0  on Ubuntu 20.
