# paragraph indentation strange

I have a first line of a second paragraph (from \section title) that is not behave like other first line in other paragraph. I need it to be indented but it din't even if I put \hspace{} before it. But when I make a copy of it, I found it normal. Please help. These are the screenshoot:

• What exactly is the problem (which indentation do you want to change)? And also please post some code so that we can see your documentclass and configurations (MWE). – TeXnician May 7 '17 at 10:39
• the first image, there is an extra line in order to make an indent of the second paragraph. other paragraphs are normal. I don't want the extra line. – Enos Lolang May 7 '17 at 10:50
• Then we definitely need a MWE showing what you tried and where you failed (= lets us reproduce your issue). – TeXnician May 7 '17 at 10:57
• please always provide code that reproduces the problem, it is very hard just to debug from an image. either you have \flushbottom and that is the only way tex can make the last line reach the bottom of the page, or you have a spurious space at the end of the paragraph, hard to tell – David Carlisle May 7 '17 at 10:57
