Open the project, then select a line for example, right-click to select properties -> new window open with properties, then click on the arrow to select a line type -> first time, list of lines open on wrong place (bottom right : sample image). on the second try, it is OK.
Same thing with colors.
When I try to change label color, tab change automatically to General and my changes are lost. I must redo the change and hurry to apply before the tab change automatically (difficult to take print screens of that).
Not found my settings.xml file.
Here is my project file.
