I cleared all bombs using round booster, why did it still have a bomb explode when they were all cle

Here's a screenshot AFTER I had to pay 10 gold to continue playing. I used the round booster (don't know names) that clears all of the same color candies. The only bombs I had left, I thoroughly checked prior to using, were all green. It exploded all remaining bombs (green) but then the level failed because a bomb went off yet all bombs were destroyed by the booster. I want my gold back. Also, as in the picture, the green bomb showed back up 1 space down from where they were but it now lists 5 moves left. There are a lot of annoying glitches and I have spent a lot of saved up boosters and gold because of them. I reached out to King a few times but I guess they are either ignoring players or they are on a permanent vacation.
