"Some" VST Insruments are out of tune.

I’m not sure what the hotfix mentioned above might be, but since downloading SE3 I’ve noticed that the Trumpet Combi (used with Dorico and the Small Flute Organ) is quite flat (-25 cents or so). This was NOT a problem with SE2. What has changed? And how can I solve the issue without readjusting pitch in every previously scored piece?
