I am not sure if this is bug or configuration issues.

I was not able to find any resource around this or any associated bugs.

I have corporate installed and configured Jenkins 2.263.3 with Active Choices (uno-choice) 2.1

Form with select drop down rendering with Name and drop down on same line and description under the drop down list:

I also have separate Jenkins 2.227.3 with Active Choices (uno-choice) 2.5.6

Same form rendering each item on a new line ...

The only difference that I can see in source code that first one is designed using TABLE HTML elements and second using DIV

Is this bug or configuration issues?

I want to have on my separate instance UI like on the first screenshot.
