FloatingLabel returns the k-state-empty class when value is 0. This is a bug as 0 is a valid value, likely due to a conditional on numericValue.

My temporary fix is editorValue={numericValue !== undefined && numericValue !== null ? 1 : 0}

You can see the bug in action if you set the numeric value to 0 in this example:  https://www.telerik.com/kendo-react-ui/components/inputs/floating-labels/

Thanks.

update to my temp fix:

My temporary fix is editorValue={numericValue !== undefined && numericValue !== null ? "1" : ""}
