Style line does not change

Dear Users,

we get very offen situation in which we have to change line style (in attachemnt) to grey one (as on picture below)

Unfortunatelly, very offen even we change it on the screen we have diffrent situation

For now only solution is get into attache file (references), change it, save and they come back into working file.

Do You have any other idea how to solve it better and faster?
