Composer issues all the time

Hi,

if you really try to create an article or a template its an horror with the composer to work with.
Its a great idea and it looks great too, but i face issue after issue...
Sometimes the heading changes itself, then even there is a separator- on the frontpage its not shown and the list goes on and on!

Please fix it, cause it makes really no fun in that way. If you try to create a professional article and copy/paste it from your source you will see what i mean.

I have the latest version...
Here a small example for the heading:
Also the color of the info box jumps from the desired one to another! I want blue, even its choosen it shows yello?!
