Form Controls Greyed out

I had a complicated sheet I built in Excel, but some of our people use LibreOffice Calc instead. So I opened the document in Libre and reinserted my VBA, but I had three buttons that I needed to work.

Unfortunately, I can’t seem to assign a macro to the buttons. When I went into form controls, all I have available are ‘Select, Design Mode, Form, Form Design, More Controls, Wizard On/Off’. All other buttons are greyed out and can’t be selected, and I’m not sure why.

Version: 4.1.0.4

Did you click ‘Design Mode On’ and then ‘Control’’? Having selected a control this should open the property editor for the control.
(You surely know there are 2 toolbars concerned with Forms / Controls.)

‘View’ > ‘Toolbars’ : Select ‘Form Design’ and ‘Form Controls’.,

Where are either of those things? I don’t see anything that says ‘Design Mode On’ or ‘Controls’. You should really include screenshots with UI based answers.

Quoting @Umaroth: “You should really include screenshots…”
Fell free to do so if you once write an answer. I prefer a few clear words where applicable.
