Summary

UI manager: boolean values do not appears in configuration forms with Yaml config format

Don't know if it's related to the Yaml config format, but in UI manager all booleans fields values and not displayed in forms, neither on startup with a fresh custom config, nor after changing their values within the UI, they still appears blank (I've attached a screenshot). It's not related to a specific browser. I've tested with Chrome, Firefox and Safari.
