Dorico will not play Microtones on Strings

HI there, I composed a short microtonal string quartet about a year ago in dorico 4 and it had no issues with microtonal playback. But I open the project today to just tinker around with it and improve the quartet and Dorico refuses to play the microtones even though they are clearly notated. Did Dorico drop support for microtonal playback or is this just a bug?

Fixed it just, had to change instruments and change them back lol
