For a lot people like me, who update the app to the App Store version, then re-install the old version because there is no list control on the new version, I've found a way to make the old version work.
You simply need to open the panel and click off one of your list, then click it back on. ABP will simply show you a alert saying 'Rule list compilation failed', just click OK and ignore it.
Then you will find it works again, at least for me.
The way I think, it probably will show the alert again and again whenever there is a change in the rule. Just ignore it.
