I can’t say … maybe your abf is not well configured. Try to remove the configuration file ~/.abfcfg and rebuild a new one. You may also post it here so I can read but absolutely don’t post it here unless you removed the password field, of course.
First you should update the file .abf.yml with the new source. Then you may make a pull request to the official github repository and open a package update request on bugzilla specifying there you have already made a pull request. Also you may try to build the package on ABF a publish it in you personal repo either using the web interface (suggested) or using abf build commands (but you may need to read documentation before to use it properly).
I guess he’s waiting for new release or even new version. Maybe he hasn’t had the time to fix it properly yet.
