Rich Text Editor Custom Toolbar

Hi All, I am using latest version of Rich Text editor.   My Custom toolbar advanced setting looks like below. Result does not have Underline, I can see all other button. Anybody facing this issue ? or knows how to solve?

Seems that the underline button only shows up when using the full toolbar and is ignored when using a custom setup.

Easy to reproduce so I would suggest creating a ticket for this with support as this is a widget published by Mendix themselves.
