Where are the cron triggers in OH2-RC1 (PaperUI)

Hi,
I installed the OH RC1 today and the rule engine seems a little bit confused, when is configured by the PaperUI.
First I have to configure all rules again, because the won’t get IDLE from not initialized because the items are missing. After I created new Action/Trigger with the PaperUI, them are working.
But i have some Timebased Triggers and the cron trigger is missing in the trigger type dropdown.

The message in the events.log from the old timebased rule:

2017-01-17 21:17:06.423 [RuleStatusInfoEvent       ] - rule_2 updated: NOT_INITIALIZED (HANDLER_INITIALIZING_ERROR): Missing handler
 'TimerTrigger' for module '1'
