Are you using hot air or just soldering iron for those jumpers?

@chenyuchih it is a bit difficult to identify exactly which component you are pointing to. A image straight down somewhat zoomed out would work better. Right now it looks like the component you are pointing to is L4400 which is a 47NH-1.3OHM inductor in a 0402 package
