All my text entries on PMC look like this after posting.

line 1

line 2

line 3

line 4 etc

I type like this though
line1
line2
line3
line4

Always have to edit post after posting them to remove the white spaces between lines.
What am I doing wrong, or is that just a buggy thing on PMC?

Edit.. it is 6:12 am Sunday morning, all nighter. Just noticed this is bedrock chat help, lol.
Cannot see where to delete this post. /DOH!
