Muse Strings dynamics playback

So, check out this piece of mine, I suggest just soloing the strings. I have added pretty clear dynamics to the whole piece (in my opinion), but there are many places where the hairpins aren't executed well and when the next dynamic comes, the sound suddenly 'jumps' to the new dynamic and it is very noticeable and weird, instead of being smooth. I thought this was to do with the anchor points where the dynamics are attached to. This was the problem in the beginning of the piece and I solved it by adjusting those anchors. However, later on this solution does not apply (and most of those anchors later on are exactly where they're supposed to be).
Sometimes, inside a mezzopiano, for example.. I also write <>, by which I mean to tell the program to just do a gentle lift and release in dynamics, not necessarily reaching mezzoforte in the middle. Sometimes, there's a slightly bigger gap between the hairpins, like this: < >, and by this I mean: lift a little, maintain the dynamic and finally come back again to the starting point.

Anyway, how can I get rid of those sudden dynamic jumps / shifts? What is the solution?
