Incorrect playback of the "fp" following each other

The first "fp" is played as expected, but the second does not work, and (as shown in the attached recording) the crescendo hairpin also does not work (Instead, the sound becomes the opposite - quieter)

Additional context

The same applies to other dynamic abrupt volume changes, such as "ffp", "fmp", "f-mf" (why "f-mf" and not "fmf", because "fmf" looks ambiguous, so in this case it is worth resorting to special separators (they are in the SMuFL) for combined dynamics. A hyphen is the best option (in my opinion)).
Currently, such designations in Musescore do not work at all as they should (based on the spelling). Instead, the volume corresponds to the last (manually written) sign ("ffp" sounds like "p", "fmp" sounds like "mp", etc.) I understand that there are no such designations in the SMuFL, but this does not exclude the possibility of their use in modern music ("ffp" is especially widespread)

@RomanPudashkin @matthewreadbass @konradglas not sure whose end the fix for this would be on, so tagging you all :-)
