Bootswatch/flatly looks like standard bootstrap in server

I have this ASP.NET MVC web application where I changed the standard Bootstrap.css (version 3.1.0) for the Bootswatch.css(flatly - version 3.2.0). I kept the original bootstrap.js file.

Well, when I run the app on my developing computer the styles (colors, sizes and so on) are accordingly with what I saw in the Bootswatch/flatly site, like the image bellow:

However, running the same app on the server the styles are more likely with the standard Bootstrap (colors, sizes and so on), like the following image:

In Content folder there are the following files:

• _bootstrap.css (original standard twitter-bootstrap.css file)
• bootstrap.css (bootswatch/flatly file)
• bootstrap.css.map (from original twitter-bootstrap)
• bootstrap.min.css (from original twitter-bootstrap)
• bootstrap-theme.css (from original twitter-bootstrap)
• bootstrap-theme.css.map (from original twitter-bootstrap)
• bootstrap-theme.min.css (from original twitter-bootstrap)
• bootswatch.min.css
• ... some other css files

So I ask how can I fix this. I'd like to have in server with the same look as in the developing computer.

Asking in other forums I got a solution.

I took bootstrap.css file (actually bootswatch/flatly css file) from css bundle and referenced it in _Layout.cshtml.
