It is, after all, FREE, so you have to get used to it.

Left click on the command EXPLODE.  
Left click (or Window click) to select drawing object(s).  
Right click to ACCEPT.  
Right click and chose EXPLODE (again) from the drop down menu.

Many commands work similarly.  Three (+) decades in AutoCAD here (since before its inception).  There is a learning curve to LibreCAD, trial and error, but progress IS being made - and I LIKE IT, 'cause it's FREE.  The AutoCAD alternative is nearly $3K for an annual license...and THAT is NOT going to happen in retirement.
