Drawing maximized on startup, and Layer List Widget missing [SOLVED]

LibreCAD Version: 2.1.2
OS: Ubuntu 18.04
Distribution: Linux Mint 19.3

On starting LibreCAD, the drawing is always maximized, even for existing drawings, even though "Start with main window maximized" in Startup under Application Preferences is disabled.

Also, the Layer List is not visible anywhere, even though it is enabled in the Dock Widgets.

Have to manually resize the drawing every time on startup, and disable/enable the Layer List.

Please advice.

Thank you.

You may try Application Preferences - Defaults - Clear settings - All.

Worked like a charm. Thank you.
