XF 2.0 If first line in post is centered, than all text get centered

[Sunka]

I have some problem with post.
If I center first line of post, than all post get centered and firs row combined with second.
In bbcode view all look right, and on preview post also all look correct, but when I publish post, all text get centered.

Solution is to begin write on 2. row (leave 1st row empty).
Is there some template where could be left unclosed bbcode or something like that?


Example:

first row text
second row text 
third row text

I tried to center first row

[center]first row text[/center]
second row text
third row text

But what I get after publishing is

[center]first row textsecond row text
third row text[/center]
