Something up with custom.css in easyblog

I am trying to make a few changes to the look of easyblog.

Mostly modifying: /templates/[my-template]/css/custom.css has worked just fine.

Unfortunately, I cannot seem to make changes to composer-manager.

I've included the following in my custom.css file:

.eb-composer-manager .eb-composer-field-content {
height: 31px !important;
}

but it's not showing up.

I've also tried applying this change to a file called: /templates/[my-template]/html/com_easyblog/custom.css as describe on this easysocial issue: http://stackideas.com/forums/css-1

but I'm not seeing any of the css changes in this file in the generated HTML.

Have I missed something, made a mistake or could there be a problem in easyblog?

Thank you for the help.
