Kashidas in 7.5 seem to be broken

I have some ghazals which I formatted in LO 7.4 (and before that). I have tried opening the same files in 7.5 and the kashidas are broken. I can’t see how to fix them (nor why I should fix them). This is a complete show stopper. I have several hundred documents formatted in 7.4 which look OK.


please send sample file .odt
