Playback plays diminuendo instead of crescendo from "ff" if there is "p" set in the bar after

I am not sure if this happens always, or only after executing some specific sequence of settings. But in short, what I did was:

1. Set a few bars to "ff" dynamic marking
2. Set the same few bars to "crescendo"
3. In the next bar after that, set "p" marking for the rest of the score.

Expected result:
Playback plays a crescendo from "ff" (presumably to "fff") in the bars marked as such, and then abruptly switches to "p" in the next bar.

Actual result:
Playback completely ignores the crescendo marking, and decides to play a diminuendo from "ff" to "p" instead.
This happens even if the last note in the last bar of crescendo is marked as "fff" - in this case the diminuendo still happens, but only that last note is played in "fff".
However, the crescendo is played as expected if I remove the "p" marking.
I wanted to try a workaround and add a "sp" marking instead of "p", but it is not available in the palette, as far as I can see.
