UI Rendering Issue with State Machine

[stellarpower]

Studio version: 1.6.0
Ubuntu 22.04 AMD64

Not built from source in a bit so not tested against master branch.

When adding an Action node in the State machine, and an action that sets a parameter to a feedback value on all channels, the sidebar in the State Machine UI window is not rendered properly the first time.

MRE:

Set up a state machine as so and save it:

Either close the state machine and open another, or restart Studio. Now open the MRE state machine example back up.

The drop-down boxes are rendered as such:

Note the incorrect spinbox for the value - we should be prompted for a lineedit for the feedback value we wish to use. I was scratching my head a bit as to how this was meant to work until I realised it was a rendering issue!

Thanks!
