Figure caption indent problem

Question

The last lines of my figure captions are indented too much or centered. I use floatrow package which usually doesn't conflict with LaTeX. Is it possible to fix this?

My preambles are as follows:

\usepackage[font=small,format=plain,labelfont=bf,up,textfont=it,up,indention=.5cm,labelsep=period,justification=centerlast]{caption}
\usepackage{floatrow}
\floatsetup[table]{capposition=top}    
\usepackage{caption}
\DeclareCaptionFormat{myformat}{#1#2#3\hrulefill}
\captionsetup[figure]{format=myformat}

Answer 1

Remove the justification=centerlast option from the caption package.
