Arabic is not supported

I have the Studio version of DaVinci Resolve Release version 15.0 and i can write in Arabic on clips using the edit application part of resolve. This feature was there since early times. But Now it is not the case when I try to write in Arabic fonts using Fusion. So there is an issue when typing using Arabic fonts in Fusion. You can see Arabic fonts, but they are not connected as it should be. they are treated as Latin alphabet.
