Adding dynamics to hairpins

Sorry if this has already been discussed, I could find anything about this exact issue. Just curios why Dorico creates an extra hairpin in this situation, where I’ve forgotten to add a dynamic at the end of the hairpin. I’m curious if there’s a better way to handle this? I’d also like to understand why this happens. Thanks!

You might find a more reliable result if you select the bar rest immediately after the end of the hairpin, input a fresh pp there. Dorico should automatically show it to the left of the barline (as there’s no note in that bar, only rests) but if necessary, you can press Ctrl/Cmd-Alt/Opt-Left arrow to nudge the pp rhythmically to the left (in increments set by the rhythmic grid, shown in the bottom left of the window).

Ok, thanks. I’ll get in the habit of doing that!
