That’s how it works. If only appears when you create the raffle. I didn’t show it in the edit because this obviously can bring some issues, like a user participating when shouldn’t be. I wouldn’t like to know, for example, that I was required to have 1000 posts and 100 rep points to participate while others managed to participate with less than that just because the raffle submitter wanted to accommodate some buddies or something like that, then he change, people gets in and then he goes back to original values.
I would suggest you to copy everything and recreate it or even change it directly in your DB. I can also provide a file change tomorrow in the morning so you can make it work as you wish in your install. I’m not able to show you today, sorry.
Post is a post. It is a content and can’t be translated. It should be done using default language since it is an automatic action fired by a task and not by a user. Is it not being created in the default language? If not, please submit a bug to my tracker on my support board.
