Based on what I can see in your screenshots I would find paragraph marks which have a lowercase letter in front of them and replace the return with a space
Find: ([a-z])^13
Replace with: \1space
Wildcards on

You can also eliminate all leading spaces by selecting all then setting centre alignment and then left alignment. This just takes three keyboard shortcuts Ctrl-A, Ctrl-E, and Ctrl-L
