Moving up one more step, these are 4 hit blockers. First you need to remove the middle blocker and the 2 rows on either side of the middle. Then you can finally work on making some matches and clearing up room. It’s not the most difficult level and setting off the striped candies is relatively easy even just swapping them takes out 2.

The fastest way to collect the orders is a color bomb/striped candy combo, but it is not necessary to get that to beat the level.
