Rounds, Scores, Clan War "Playing"

HI
First of all congratulations for the cool theme!
The public of my website liked it a lot.
I have a few questions regarding the clan matches.

1) When I create a new clan match with date in the future it apears in the “Next Clan Matches” box. When the corresponding time is due, the match moves from “Next Clan Mathces” to “Latest Matches” box with the tag “Playing”. Then after some time, the tag “Playing” disappears. HOW DO I CONFIGURE THE DURATION OF A MATCH, SO THAT IT DISPLAYS THE TAG “PLAYING” FOR THE CORRECT AMMOUNT OF TIME? How do update the scores of a match in the middle of the match and revert it to “Playing” status?

2) I created a new match and I mistakenly added several rounds. Each round has separate scores. Now I would like to remove thor extra scores. HOw do I eddit the number of rounds? I can see only an “add” button, no “remove” button. Now I have several clan matches with several 0:0 scores (see attached image)

Thank you
