Predicitions on started match?

Hi there,
I am using the plguin + many of the extensions, but I have a “problem” – I’ve installed the “snow only open matches” extension, but still I can change my prediction on a match that should be already started.

For example for testing purposes I set a single match with starting time after 5 mins. Then I give my prediction. Then I am waiting for 45 mins and after that I can still give / change my predictions on this match.
My question here is after how much time the match is counted for closed? Shouldn’t the default behavior be – when you give prediction for a match and it start – the system close the predictions for all users? I thought that the extension will do that, but at the moment I can see than matches are removed from prediction for example after 24 hours – on the next day (I tested it when I set the starting time on the same testing match one day ago – and it dissappeared)

Please, elaborate!
Thank you!
