Unable to justify

[Eagle Warrior]

I set the initial part of the page to center.
Now it won't justify current or subsequent text. If I click left justify it moves the text slightly to the right
I click Center and it re-centers it again. I am unable to justify.
I did click the big text T.
Simply put, I am unable to justify anything??

Additionally and relevant, what are the black right pointing arrows?
Why sometimes when I try to select some text do I get either a red line on top of the text, red lines around it or see a magnet?
