I guess the official Fedora package was upgraded in remote repos and was 
therefore selected as an upgrade of your package. This happens if both 
packages have the same name.

You basically have two options to do what you need:

1) Rename the package [1]
2) Bump the epoch so that the EVR of your custom package is always higher than 
the official one

However, both of these options have some potential implications for stability 
of your system and you should know what are you doing before choosing one of 
them.
