Random event settings

Using the random event setting and having convoy and many other events in there, what's static button do? Seems nothing is getting called up to start. 

Static means that it is always the fixed time
E.g.: 1:30 then the event always starts at 1:30

If you remove the static button an event starts every 1 1/2 hours

Changed Status from Pending to Closed

I tried setting it to :30 so a random event would start every 30 minutes and it only starts them every hour. 

Can we reopen the topic, as Anton says, it doesn't seem to work.

I specified Random Start with times and defined which events come into question.
Unfortunately, an event random is never selected - it says in the console every time:
Logs:

[Eventmanager] 1
[Veranstaltungsmanager] 2 2
[EventManager] ZUFÄLLIGER START
[EventManager] 4 Flugveranstaltungen beginnen  

Can you fix this promptly? I know they just adopted it, but it would still be nice if this feature worked too.
